custom report through python odoo 9

Question

How to pass multiple module data to a QWeb report? Is there something similar to passing dictionary in rendering html from controller?

Answer 1

If you want to run specific code before your report prints or pass custom data to your template for rendering you can create an Abstract model which defines a render_html function so that your function will run when printing the report rather than the generic odoo function. This is referenced in the documentation HERE

Take a look at this example.

from openerp import models, fields, api, exceptions

class YourReport(models.AbstractModel):
    _name = 'report.your_addon.report_template_id'

    @api.multi
    def render_html(self, data=None):
        report_obj = self.env['report']
        report = report_obj._get_report_from_name('your_addon.report_template_id')
        model1_docs = self.env['your_addon.your_model1'].search([('something','=','something')])
        model2_docs = self.env['your_addon.your_model2'].search([('something','=','something')])   
        docargs = {
            'doc_model': report.model,
            'model1_docs': model1_docs,
            'model2_docs': model2_docs,
        }
        return report_obj.render('your_addon.report_template_id', docargs)

UPDATE WITH MODIFIED CONTEXT:

To call your report with a modified context try the following (untested). I could not find any examples of calling reports with modified context however did not look extensively.

ctx = self.env.context.copy()
ctx.update({'domain':[('something','=','something')]})
self.with_context(ctx)
return {
    'name':'Report',
    'type':'ir.actions.report.xml,
    'report_name':'your_addon.report_template_id',
    'report_type':'qweb-pdf'
}

Then from within your report function we defined earlier you should be able to access context through your environment.

domain = self.env.context.get('domain')

You will need to create a function in your wizard which calls the report passing the context.
