I am working on module. it has a button, its name is creates, as shown in following code.

<button name="creates" string="Create" type="object" groups="base.group_erp_manager" /> def creates(self,cr,uid,ids,context=None): for id in ids: deg_obj=self.pool.get('deg.form').browse(cr,uid,id) pr=int(deg_obj.categg_temp) ctx=dict(context) ctx.update({'default_pr':pr}) return{ 'view_type': 'form', 'view_mode': 'form', 'res_model': 'product.product', 'context': ctx, 'type': 'ir.actions.act_window', 'target': 'current', }

when i click this button i get

Integrity Error The operation cannot be completed, probably due to the following: - deletion: you may be trying to delete a record while other records still reference it - creation/update: a mandatory field is not correctly set [object with reference: name - name]

On my server log i have

My first question is. Why I am getting an error with sql insert command although there is nothing like insert related to creates method. It simply opens a form where i will press save button or something to save value. Secondly, how i can bypass this and move to next step where i can create item.

NOTE: I have Edit, View methods and buttons too, which simply opens Value in View and Edit mode. but have same issue with them too.




I have provided `name`:'' in defaults. Have same issue. This class deg_form is inherited from product.product. I want to open Edit/create form on button click. This button's method is never called. All i get is exception of name
