`setLang` alters the "browse" context of the documents
being printed, but it must also discard any values
already cached, as they could be using a different language.
This is the case when the report uses translatable fields
on `res.partner`, because `setLang` is usually called
with the target partner language, hence prefetching
the translatable fields with the user's language instead
of the partner's language.
E.g. `setLang(o.partner_id.lang)` will cache any
translatable field on `o.partner_id` in the language of
the *user*, not the *partner*.
While keeping the compatibility for reportlab 2.5.
Splitting the text node on line breaks '\n' leaded to orphans ending tags,
like '</font>', which is regarded by reportlab 3.0 as a paragraph,
and reportlab therefore surrounded these tags by <para> tags,
which leaded to not syntax correct html like
<para></font></para>
To test this patch:
- While having reportlab > 3.0
- Create a rml report containing (at least) '<font>\n</font>'
- Then print the report. It must not crash (obviously)
From reportlab 3.0, empty plaintext paragraphs do not lead to a break line anymore.
Before release 3.0, paragraphs having tags but no plaintext leaded to a break line.
This patch aims to recover the behavior of reportlab releases < 3.0, as
<para><font color="white"> </font></para> is used in allmost all rml reports
The current patch is not considered as clean, but we did not find any better solution.
If someone find a parameter to pass to reportlab in order to bring back the old behavior of reportlab
he is welcome to provide the better patch.
Besides, in reportlab 3.0, splitlongwords has been introduced as parameter,
to allow to break long words. The default value is True.
This parameter seems to break the columns headers
(it splits the text within the column header)
We therefore take the choice to not activate it, as it was not present anyway in reportlab < 3.0
To test the good behavior of this patch:
While having reportlab < 3.0 (2.5 for instance), print a draft invoice
Then, upgrade to reportlab > 3.0 (3.1.8 for instance), print the same draft invoice.
The generated pdf must be (allmost) identical, in particular concerning spaces.
Specifically, the space between the partner address and his phone.
Save the NumberedCanvas state before doing a page reset.
The order of execution when rendering an rml report is the following:
1. init canevas (_pageNumber = 1)
2. render the page element
3. if still pages to render, afterPage method
4. if still pages to render, showPage method (_pageNumber += 1)
5. back to step 2 for each page
6. draw the ResetPage element (setting flag _doPageReset=True)
7. end the document build with afterPage & showPage method
The PageReset element should be executed at the end of the rendering of a story (subdocument) to reinitialize the page numbers to 0 (for new story) and insert the pageCount element for that story with the total number of pages (needed if want to use tag <pageCount/> in rml).
In case of NumberedCanvas (e.g. used in Trial Balance report), the numbering is generated at the end of the build using the _saved_page_states dict in the canevas.
To have an accurate _saved_page_states content, it needs to be saved before the pageReset.
Fixes#2225
Commit b6a7402 (reverted at f8671cb) was almost correct, the PageReset should be added at the end of each stories but only if we have one more stories.
The PageReset will force the page count to be reseted at zero which means that last page of report would have been at zero.
This patch comes with a related patch on addons which
fixes a lot of cases of terms that were not properly
translated in reports, due to improper use of the
translation system. The addons patch also adds a
lot of missing entries in the POT files.
