SENAITE IMPRESS is basically a rendering engine for HTML documents to PDF. It supports any kind of international paperformat with their corresponding paper dimensions, portrait and landscape orientation and merging of multiple PDFs to one document.
SENAITE IMPRESS is included in the SENAITE LIMS distribution, so no further installation steps are needed.
To learn more about how to install SENAITE, please follow the SNEAITE Installation Manual
SENAITE IMPRESS opens automatically when a Sample is published, prepublished or repupublished.
The above screenshot shows 4 Analysis Requests in the workflow state "Verified". Select them and click the "Publish" Button.
The SENAITE IMPRESS preview allows you to change the report template, paperformat and the orientation.
The "merge" checkbox creates a single PDF, even when no multi-template was selected.
The button "Save" will do the following actions:
- Generate the PDF and store it below the corresponding Analysis Request
- Redirect to the "Analysis Reports" view of the customer
- Keep the current Workflow state (Publication is only done by sending the Email)
The button "Email" will do the same actions as "Save", but redirects directly to the Email view.
A new tab Analysis Reports will be available for Clients, which lists all generated PDF reports for all Analysis Requests of this client. Reports can be selected in this listing for email delivery. This also allows to send multiple PDF Analysis Reports in a single Email.
Selecting one or more Reports allows to send the generated PDFs to the selected contacts of the Analysis Request.
If the Email was successfully sent, the corresponding Analysis Requests change the state to "Published".
After you clicked the "Send" button, the Email with the attched reports are delivered to the selected recipients.
The workflow states of the Analysis Requests have changed their state to "Published".
Note
In the case that multiple Analysis Requests are rendered in a single Report, the contained Analysis Requests are also published when this Report was send.
Most of the labs require custom reports and SENAITE IMPRESS allows you to do that with relative ease.
The following sections will guide you through the process of creating a custom report.
The easiest way to get started with senaite.impress
is to copy one of the
existing templates in the templates/reports
folder within this package.
The smallest report example looks like this:
<h1>Hello World!</h1>
It renders a heading saying “Hello, world!” on the report.
The next few sections will gradually introduce you to using senaite.impress
.
We will examine single- and multi reports, Zope page templates and the super model.
Once you master them, you can create complex reports for SENAITE.
The difference between single- and multi reports is that a single reports receive a single report object, while multi reports receive a collection of report objects.
senaite.impress
uses the report name to distinguish between a single- and
multi report. A report starting or ending with the workd Multi
, e.g.
MultiReport.pt
or PublicationReportMulti.pt
will be considered as a multi
report and it will receive all selected objects in a collection
.
All other reports, e.g. Default.pt
, HelloWorld.pt
, SingleReport.pt
will be
considered as single reports and it will receive the single report as its model
.
The most basic single report looks like this:
<tal:report define="model python:view.model;">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
</tal:report>
It renders the ID of the model (in this case the Analysis Request H2O-0001-R01
) on the report.
To render a multi report, we need to copy the previous template to MultiHelloWorld.pt
.
The most basic multi report looks like this:
<tal:report define="collection python:view.collection;">
<tal:model tal:repeat="model collection">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
</tal:model>
</tal:report>
It renders the IDs of the model (in this case the Analysis Requests
H2O-0001-R01
and H2O-0002-R01
) on the same report.
Change between the templates HelloWorld.pt
and MultiHelloWorld.pt
to see how
the two selected Analysis Requests render either on two pages or on one page.
Zope Page Templates is the main web page generation tool in SENAITE.
Page Templates are recommended way to generate reports in senaite.impress
.
We have already seen a small example how to use the Template Attribute Language
(TAL). TAL consists of special tag attributes. For example, we used a dynamic
page headline in the previous reports:
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
The Super Model is a special wrapper object for database objects in SENAITE.
The advantage of Super Models is that they provide transparent access to all content schema fields in a preformance optimized way.
Also see: https://github.com/senaite/senaite.app.supermodel#readme
For example the content type
Analysis Request
in SENAITE defines a computed field SampleTypeTitle
.
To access this field in a report, you simply traverse it by name:
<tal:report define="model python:view.model;">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
<h2>
Sample Type:
<span tal:content="model/SampleTypeTitle">
This will be replaced with the Sample Type Title
</span>
</h2>
</tal:report>
Now it should render the title of the sample type below the ID of the Analysis Request:
senaite.impress
uses Bootstrap 4 as the main front-end component library.
Each report will therefore follow these style guidelines and can be easily extended.
Please note, that you should start with Rows as the top level HTML element inside a report to maintain the borders of the selected paper format.
<tal:report define="model python:view.model;">
<div class="row">
<div class="col-sm-12">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
<h2>
Sample Type:
<span class="text-secondary"
tal:content="model/SampleTypeTitle">
This will be replaced with the Sample Type Title
</span>
</h2>
</div>
</div>
</tal:report>
To customize the style of your report, it is recommended to add the CSS style inline.
<tal:report define="model python:view.model;">
<tal:css define="laboratory view/laboratory;">
<style type="text/css">
html, body { font-size: 1em; }
h1 { font-size: 160%; }
h2 { font-size: 120%; }
@page {
font-size: 9pt;
@top-left {
content: '<span tal:omit-tag="" tal:content="laboratory/Name"/>';
}
@top-right {
content: "<tal:t i18n:translate=''>Page</tal:t> " counter(page) " <tal:t i18n:translate=''>of</tal:t> " counter(pages);
}
}
</style>
</tal:css>
<div class="row">
<div class="col-sm-12">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
<h2>
Sample Type:
<span class="text-secondary"
tal:content="model/SampleTypeTitle">
This will be replaced with the Sample Type Title
</span>
</h2>
</div>
</div>
</tal:report>
Please also see the Paged media CSS properties to learn how to control the presentation of content for print or any other media that splits content into discrete pages.
The Report View acts as a controller for the multi- and single reports. It provides code logic to group, sort and extract the data of the report model/collection.
Methods (functions) of the Report view are referenced by the keyword view
in the template
and provide the business controller logic between the plain data object and SENAITE LIMS/HEALTH.
Report views can be customized per report for any specific report behavior and model.
The standard report view for models of the type Analysis Request is located here: https://github.com/senaite/senaite.impress/blob/master/src/senaite/impress/analysisrequest/reportview.py
<tal:report define="model python:view.model;">
<tal:css define="laboratory view/laboratory;">
<style type="text/css">
html, body { font-size: 1em; }
h1 { font-size: 160%; }
h2 { font-size: 120%; }
@page {
font-size: 9pt;
@top-left {
content: '<span tal:omit-tag="" tal:content="laboratory/Name"/>';
}
@top-right {
content: "<tal:t i18n:translate=''>Page</tal:t> " counter(page) " <tal:t i18n:translate=''>of</tal:t> " counter(pages);
}
}
</style>
</tal:css>
<div class="row">
<div class="col-sm-12">
<h1 tal:content="model/id">This will be replaced with the ID of the model</h1>
<h2>
Sample Type:
<span class="text-secondary"
tal:content="model/SampleTypeTitle">
This will be replaced with the Sample Type Title
</span>
</h2>
<hr class="py-1"/>
<div class="text-muted font-italic">
Published <span tal:content="python:view.to_localized_time(model.DatePublished)"/>
by <span tal:content="python:view.current_user.get('fullname')"/>
</div>
</div>
</div>
</tal:report>
Until now we created all reports on the file system within this package, which
is not the recommended way, because with future updates of
senaite.impress
, these changes will be lost.
Therefore it is recommended to create a new SENAITE Add-On Package and put the custom reports in there. Note that the naming of the report template is important if you are customising a multi-sample report - you MUST start or end the template name with the word 'multi'.
In your new package configure.zcml
you have to specify the folder where your reports live:
<configure
xmlns="http:https://namespaces.zope.org/zope"
xmlns:plone="http:https://namespaces.plone.org/plone">
<!-- Report resource directory -->
<plone:static
directory="reports"
type="senaite.impress.reports"/>
</configure>
This will integrate the reports
directory within your package into the search
path of senaite.impress
.
It is recommended to have a report controller view in place to avoid heavy Python logic in the domain of the page template.
To create a custom report controller view, you need to have first a custom
browser layer defined in your interfaces.py
:
from bika.lims.interfaces import IBikaLIMS
from senaite.impress.interfaces import ILayer as ISenaiteIMPRESS
from senaite.lims.interfaces import ISenaiteLIMS
class IMyLIMSLayer(IBikaLIMS, ISenaiteLIMS, ISenaiteIMPRESS):
"""Marker interface that defines a Zope 3 browser layer.
"""
and register the layer in profiles/default/browserlayer.xml
:
<layers>
<layer name="my.lims"
interface="my.lims.interfaces.IMyLIMSLayer" />
</layers>
``**
Then you can register the controller view in `configure.zcml`:
```xml
<!-- View for Single Reports -->
<adapter
for="zope.interface.Interface
my.lims.interfaces.IMyLIMS"
name="AnalysisRequest"
factory=".reportview.MySingleReportView"
provides="senaite.impress.interfaces.IReportView"
permission="zope2.View"/>
<!-- View for Multi Reports -->
<adapter
for="zope.interface.Interface
my.lims.interfaces.IMyLIMSLayer"
name="AnalysisRequest"
factory=".reportview.MyMultiReportView"
provides="senaite.impress.interfaces.IMultiReportView"
permission="zope2.View"/>
And create your own reportview.py module:
from senaite.impress.analysisrequest.reportview import MultiReportView
class MyMultiReportView(MultiReportView):
"""My specific controller view for multi-reports
"""
def __init__(self, collection, request):
logger.info("MyMultiReportView::__init__:collection={}"
.format(collection))
super(MultiReportView, self).__init__(collection, request)
self.collection = collection
self.request = request
Note: Since version 1.2.4 it is also possible to register a multiadapter that adapts the current rendering context, the report model/collection and the request:
<!-- View for Single Reports -->
<adapter
for="*
*
my.lims.interfaces.IMyLIMS"
name="AnalysisRequest"
factory=".reportview.MySingleReportView"
provides="senaite.impress.interfaces.IReportView"
permission="zope2.View"/>
<!-- View for Multi Reports -->
<adapter
for="*
*
my.lims.interfaces.IMyLIMSLayer"
name="AnalysisRequest"
factory=".reportview.MyMultiReportView"
provides="senaite.impress.interfaces.IMultiReportView"
permission="zope2.View"/>
This would allow to use the current context where publish
view was called
can be used as well:
from senaite.impress.analysisrequest.reportview import MultiReportView
class MyMultiReportView(MultiReportView):
"""My specific controller view for multi-reports
"""
def __init__(self, context, collection, request):
logger.info("MyMultiReportView::__init__:collection={}"
.format(collection))
super(MultiReportView, self).__init__(collection, request)
self.collection = collection
self.context = context
self.request = request
senaite.impress
comes with some default templates included. It is recommended
to read the code of these templates or use them as the base for new reports.
This page template is renders single reports (one AR per report).
This page template is renders multiple reports on one report. The header and
footer will be rendered only once. The metadata of the first model (here the
Analysis Request H20-0001-R01
) will be used for these sections and the
results/remarks/attachments sections will be repeated for all models in the
collection (H20-0001-R01
and H20-0002-R01
).
This page template behaves like the senaite.impress:MultiDefault.pt
, except
that the results of all models (Analysis Requests) will be rendered in columns
side by side.
