I started learning Perl Catalyst and its awesome!!! However, I am having a little issue here with templateing.
I am trying to pass two template variables to the page (header and footer), what I did in the Controller function is
$c->stash(template => 'header.html');
//other page contents
$c->stash(template => 'footer.html');
but this only outputs the footer.html (which it should and seems logical)
What would be the way for this approach? I searched google but could not find many helpful results (at least results that I could understand and use)
You need to create a view.
https://metacpan.org/pod/Catalyst::Manual::Tutorial::02_CatalystBasics#Hello-World-Using-a-View-and-a-Template
Also, have a look at how wrappers work in TT -- they are really cool.
http://www.template-toolkit.org/docs/manual/Directives.html#section_WRAPPER
You cannot pass 2 templates in stash.Only the last value will be kept.However the to way to do this, is to include the footer template inside the header.The commands include and process are very helpfull.

maybe someone can help me on this. I am trying to generate a document via the DocumentGenerator interface. All in all this works well, except that the DocumentGenerator does not replace the Report Constants with actual values (which are defined on the report package stereotype.
This is the general flow of the document creation code (which generally works):
var gen = Repository.CreateDocumentGenerator();
gen.SetProjectConstant("ReportName", "My Project");
gen.NewDocument(string.Empty);
gen.ReplaceField("ReportName", "My Project");
gen.InsertCoverPageDocument(tags[REPORT_COVERPAGE]);
gen.InsertBreak(DocumentBreak.breakPage);
gen.InsertTOCDocument(tags[REPORT_TOC]);
gen.InsertBreak(DocumentBreak.breakPage);
gen.DocumentPackage((int)nativeId, 0, template);
gen.SaveDocument(fileName, DocumentType.dtDOCX);
I tried ReplaceField and SetProjectConstant both and one at a time before and after calls to NewDocument/InsertCoverPageDocument:
Strangely there is one constant that is being replaced: ReportSummary.
When I run the document generator via "F8" all constants are being replaced correctly.
Other project constants are being replaced correctly.
I can reproduce the behaviour on EA v14.1.1429 and v12.0.1215.
Does someone have a hint for further troubleshooting? Thanks in advance!
========== UPDATE ==========
When I use ReplaceField at the end (before the actual call to SaveDocument the following Report Constants get replaced: {ReportTitle} and {ReportName}
I discovered some workaround: when I manually remove the predefined {Report~} constants from the template and re-add them as Project Constants, their values get replaced correctly.
I will examine this further and give an update as
I did some further investigation on this and came to the following conclusion and workaround (as I have received no comments or answers on this):
I deleted all references to ReportConstants in my EA templates and replaced them by ProjectConstants with the same name.
In my code where I want to generate the documentation I (re)set all ProjectConstants with the actual values via SetProjectConstant and additionally added a call to ReplaceField to replace the constants with the actual values.
The previous mentioned calls are inserted directly before the call to SaveDocument document.
tags.ForEach(t =>
{
if (string.IsNullOrWhiteSpace(t.Key)) return;
generator.SetProjectConstant(t.Key, t.Value);
generator.ReplaceField(t.Key, t.Value);
});
generator.SaveDocument(fileName, DocumentType.dtDOCX);
If someone comes up with a better resonse or explanation for the behaviour I am happy to accept this as answer.
I have also found that when you call ReplaceField on these project constants in a CoverPage template, the formatting defined in the template is overwritten. It seems that some of the SetProjectConstant calls actually set the values as you would expect, and the rest do not.. hence the need to call both sets of APIs.
I'm trying to crawl a site and to do so, I'm using Scrapy. So, when doing requests to nested pages, the procedure usually gets the the information correctly on the first trials, but, on later requests the nodes starts to return None. I'm using xpath's functionality. Below I'm pasting some lines of the parse function:
(I tried this one with the approach of explicitly comparing the class value)
title = response.xpath('//span[#class="inlineFree"]/text()').extract_first()
(With this one I used the contains function)
view = response.xpath('//span[contains(#class,"count")]/text()').extract_first()
(I've also used this one when I found more suitable)
comments = response.css('div.commentMessage > span::text').extract()
Am I doing something wrong on paths?
Is there any reason for the crawler to stop reading the nodes correctly?
Cannot say what the problem is without the log messages or the spider code but..
What happens most of the time is that websites fo not follow a strict html structure .For some properties the 'title' may be inside the span
but for the next iteration it may be
span[#class="inlineFree"]/h1/text() or or any other tag
so you should check the html for those returning None
I am using Catalyst::View::Wkhtmltopdf but issues are araising,
got the error
Caught exception in wealthe::View::Wkhtmltopdf->process "Void-input at /usr/local/share/perl5/Catalyst/View/Wkhtmltopdf.pm line 98."
When checked found its some issue with template, I have added the following config in myapp.pm
'View::Wkhtmltopdf' => { command => '/usr/local/bin/wkhtmltopdf',
tmpdir => '/usr/tmp',
tt_view => 'TT',
}
Template name is TT.pm under View and TT.pm is rendering correctly,
I have made Wkhtmltopdf.pm file under View with the following contents
package myapp::View::Wkhtmltopdf;
use Moose;
extends qw/Catalyst::View::Wkhtmltopdf/;
PACKAGE->meta->make_immutable();
is there anything else I need to get it working.
My experience with the PDF writing perl modules on CPAN is that every option is either:
extremely simple, but capable of only very rudimentary output
fully featured and capable of professional PDF output, but hideously complex and requiring pretty deep knowledge of PDF internals
We gave up.
Instead of trying to generate PDFs with perl natively from scratch, we attacked the problem by building the pages we wanted to render as PDF with Template Toolkit (in most cases reusing existing templates with different wrappers), and used the excellent wkhtmltopdf to handle the conversion to PDF.
Since then, Catalyst::View::Wkhtmltopdf has become available that makes this even simpler.
One of the easiest way is to create a (quite simple) HTML page then convert it to PDF: https://metacpan.org/pod/PDF::FromHTML
It needs the least amount of PDF knowledge.
The other module could create PDF on the fly but they are much more complicated: https://metacpan.org/pod/PDF::API2
We have quite a number of .xqy files in several folders.
Sometimes, I need to invoke an .xqy file (via Marklogic's CQ) to test if it's working.
But I find it rather cumbersome to have to know what parameters to pass in and specify them in the xquery in CQ.
Is there a tool out there that would generate an HTML form that presents to me the parameters of a given .XQY file and invokes it when I press a "submit" button ?
If there is none out there, would somebody here know of how to make such an HTML form ? Right now, I can't seem to find any readily-available xdmp or xquery commands to tell me if an .XQY file is invocable or what parameters it expects to be fed.
Danny
The XQuery standard doesn't support introspection, nor does MarkLogic provide any functions that help with that. The closest you can get with this is using the XQDoc documentation code that is capable of parsing the XQuery code itself and producing descriptions of all function signatures within modules.
You can find more details about it here: http://developer.marklogic.com/code/xqdoc-ws
It doesn't provide a 'Submit' button, but using the XML output of xqdoc, you could make that yourself..
Good luck!
Another option would be to convert your XQuery to XQueryX and you can then process this as XML using XQuery (or XSLT) to generate an XForm or XHTML Form.
Since Danny mentioned unit testing, I'll risk plugging my own framework for that: https://github.com/mblakele/xqut
I usually run XQUT test suites in a cq buffer, but it would be easy enough to wrap one in a simple web page - with or without a form.
I'm using toLocalizedTime to output a date, as below
<span tal:content="python:here.toLocalisedTime(date.get('start_date'))"/>
This outputs eg. 2007/08/02, I'm just curious as to how one would alter the output so that it reads 02/08/2007
I'm not having much luck finding much info on toLocalizedTime, would someone point me in the right direction?
This depends on whether you have English selected as the site language (Site Setup >> Language). If so, then the default settings are used. You can change the defaults by dropping down into the ZMI, then into 'portal_properties', then 'site_properties'. The fields to change are either 'localTimeFormat' or 'localLongTimeFormat' depending on whether you pass in 'long_format=1' to the toLocalisedTime function.
If on the other hand, you have translations set up, the format may instead be pulled from the translation file for the locale selected. I'm not sure what is the easy way to change the format in this case (other than switching the site back to English). I guess you can register your own translation file but I've never needed to do that so you're going to have to look up the details.
Date string formatting follows the Python rules (http://docs.python.org/library/time.html#time.strftime).
Perhaps even more detail than you need:
here.toLocalizedTime()
is defined in the plone browser view at...
CMFPlone/browser/ploneview.py
which looks up the 'translation_service' utility, to call its 'ulocalized_time' function, defined at...
CMFPlone/TranslationServiceTool.py
which itself calls the 'ulocalized_time' function defined at...
CMFPlone/i18nl10n.py
As always, you can learn interesting things by grepping the source code ;-)
For an up to date answer for Plone 4.3 (after going through the source code)
These fields are now in the registry found at:
http://localhost:8080/yoursite/portal_registry
Then filter on "i18nl10n", which should give you the 4 fields you need to change.
