How to find out the table name for a many2many relation (Where is the many2many table name stored?)

Question

Hi,
I am trying to recover data from a broken odoo installation (uprade got screwed up).
I have exported all the tables to CSV using postgresql (psql). I would also be able to handle many2one and one2many relations.
For many2many relations, I need a way to programatically find out which database table contains the relation details (ids from both the models). I tried to get the data from the ORM "fields_get" function using xmlrpc. The  field definition returns a dictionary which has a key named '

Hi,

You can get the name of the relation table by seeing the fields definition only. Or, odoo maintains a separate table called 'ir_model_relation' containing the module id(like, Project) and the object(model) id(like project_project ) with relation tables name for that object, you can use this table to get all the relation for that particular model(object) .
Thanks

i want to explain how odoo framework create related table for many2many for exemple we have your  model1  where you created "category_id" and the other  model2  where you Create the relation with many2many
Now for each models odoo create table in Psql , so for models1 odoo create in Psql  table:model1 and for the second model Psql create  table: Model2  and for the relation many2many Psql create the third his name is  table:model1_Model2
so in odoo create this table with  underscore  and the 2 t

In Odoo 9, you can query ir_model_fields to get the table name from the relation_table column.
I'm not too sure about 7 and 8, but I think in 6.1 you could check the field definition from a fields get - something like:
self.fields_get(cr, uid, ['my_m2m_field'])['my_m2m_field']['third_table']
