How to change the sheet tag width in Odoo?

Is there a way to change the sheet width for a specific form in Odoo? I've created a css file to change the sheet tag width but all the form sheet tags width had been changed. I just want to change the width for a certain form. Is it possible?

Solution

You can delete the sheet node in your view in order to expand the width to the 100%. Just add this function to your model:

from lxml import etree
def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False, submenu=False):
    res = models.Model.fields_view_get(self, cr, uid, view_id=view_id, view_type=view_type, context=context, toolbar=toolbar, submenu=submenu)
    if view_type == 'form':
        doc = etree.XML(res['arch'])
        for sheet in doc.xpath("//sheet"):
            parent = sheet.getparent()
        for child in sheet:
            parent.append(child)
        parent.remove(sheet)
        res['arch'] = etree.tostring(doc)
    return res

That was the answer of my question 4 weeks ago

And if you have a message box, you may want to use this one to keep the order of the layout

def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False, submenu=False):
    """ Remove the sheet node keeping the elements inside """
    res = models.Model.fields_view_get(self, cr, uid, view_id=view_id, view_type=view_type, context=context, toolbar=toolbar, submenu=submenu)
    if view_type == 'form':
        doc = etree.XML(res['arch'])
        for sheet in doc.xpath("//sheet"):
            for oe_chatter in doc.xpath("//div[@class='oe_chatter']"):
                sheet.append(oe_chatter)
            parent = sheet.getparent()
        for child in sheet:
            parent.append(child)
        parent.remove(sheet)
        res['arch'] = etree.tostring(doc)
    return res

Update

There is also a community module to achieve a similar result web_sheet_full_width
