Printing invoice in proteus

Support Developer
1

i tried to “print” an invoice in, proteus (getting the file.odt) i search the webn forums, use_case (i tried to read the code) and i did not success.
what i did.

from proteus import config, Model, Wizard, Report
my_config = config.set_trytond('postgresql:///tryton',config_file='/etc/tryton/trytond.conf')
Invoice = Model.get('account.invoice')
invoice,=Invoice.find([('reference', 'like', 'AZT45')])
# invoice is the good invoice i can print the infos
my_report=Report('formo_t.report')
#now i can and i get all infos
type_, data, print_, name = my_report.execute([invoice], {})
#but there is now way i could find to transform thoses data in odt.
#the doc says report.render() I do not know what parameters to give
my_report.render('formo_t..report',my_context)
  Traceback (most recent call last) 
  File "<stdin>", line 1, in <module> 
  AttributeError: 'Report' object has no attribute 'render'*
#it seems that render is not allowed

where can i find an exemple that leads to a .odt file ? (the report is odt)

data is the rendered content.

3

i tried to save data in a file and it is not a opendocument file.

If im not wrong the AttributeError is raised because render is a classmethod and you are calling from an instance of the class instead of the class, also when you call execute you have the extension in type_.
If you want to convert the extension maybe you could take a look on Report.convert.
Hope it helps.

thank you for the link, i tried to understand that thing i allready read before posting, but i did not succed…

# *classmethod* Report.execute(*ids*, *data* ) 
>>> type_, data, print_, name = my_report.execute([invoice], {}) # << ok

# classmethod Report.render(report, report_context)
# Returns the content of the Report rendered by the templating engine. And add gettext and ngettext to the evaluation context for translatable reports.

#classmethod Report.convert(report, data[, timeout[, retry]])
#    Converts the report content data into the format defined by the Report.

>>> Report.convert(my_report,data)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: type object 'Report' has no attribute 'convert'.
>>> my_report.convert(my_report,data)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Report' object has no attribute 'convert'. Did you mean: '_context'?

the same with
# classmethod Report.render(report, report_context)
# Returns the content of the Report rendered by the templating engine. And add gettext and ngettext to the evaluation context for translatable reports.

i’ll try to read some code to understand. it would be so simple to have a 10 lines of snippet code. but it seems to be a bad ideas i do not know why.

Well it is the format that you have configured.

concernant le topic qui a été (à mon sens abusivement fermé car la question posé n’a pas été résolu) ici : Printing invoice in proteus - #8

bon, peut être que l’on en se comprend pas en anglais. et non le sujet n’est pas résolu.

data est peut être le contenu rendu, mais je ne sais pas comment le transformer en fichier .odt.

Est-ce qu’il y a quelque part sur le net un endroit on l’on voit un script qui fait .execute et qui produit un fichier .odt sur le disk ? il manque peut être une manip ou une commande ce serait gentil de la donnée car si je suis la réponse donnée, et que j’enregistre les données sur le disque je n’ai pas un fichier valide.

You can save the content to a file with the following python code:

with open(filename, "wb") as file:
        file.write(data)

Make sure to change filename with the name of the file you want. As tryton already returns the filename and the extension you can constricut it directly. You currently have:

type_, data, print_, name = my_report.execute([invoice], {})

So this may be updated to:

filename = f"{name}.{type_}"
with open(filename, "wb") as file:
        file.write(data)

Hope this makes everything clearer and sorry for having an unresolved question closed.

from proteus import config
from proteus import Model, Wizard, Report
my_config = config.set_trytond(
    'tryton_preciball_prod_72_test',
    config_file='/home/mrichez/Workspace/tryton/issues/.trytond.conf')
Invoice = Model.get('account.invoice')
invoice,=Invoice.find([('number', '=', '124100205')])
# invoice is the good invoice i can print the infos
my_report=Report('account.invoice')
#now i can and i get all infos
type_, data, print_, name = my_report.execute([invoice], {})
pdf = bytes(data)
with open("test.pdf", "wb") as f:
    f.write(pdf)

This is working for me but my reports are converted in pdf. It should be the same for an odt.
