python - Use foreign keys in unmanaged model in Django -

-

I have some unmanaged models to get data from Oracle Database, but I can not read anything in the documentation about joining tables.

I have these models 

  class Model1 (models.Model): id = Models.CharField (max_length = 200, primary_key = true) name = model.carfield (max_length = 200, empty = true, empty = true) = meta: managed = incorrect db_table = 'table_1_name' class Model2 (models.Model): Model1_id = models.CharField (max_length = 200, empty = true, zero = true) Class meta: Managed = Wrong db_table = 'table_2_name'   
 And in tables I model 1 and model 2 I am trying to join.  
 I thought I would get the data with  Model1 = models.ForeignKey (Model1)  in  obj.model1__name , but I did not work it can do.   
 
 
 The problem is nothing with unmanaged models - this is just a question of syntax.  
 The foreign declaration is correct, but related information is used through dot syntax:  obj.model1.name .

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
