ManyToMany relationship with intermediate model and admin list display with each realtion with value as diferent column

[Ignacio Soto]

Hey guys

i have an issue, i don know if it really can be done.

im using django 1.3

i have a model producto(product) and Tienda(store)

and a product could be in one or more stores, so i created a many to many 
relationship but y have a stock in each store, so i use the intermediary 
model ProductStore.

i want to create this, in the admin , product's  list display, i want to 
show each manutomany relationship as a diferent column qith the stock as 
the value.





as shown in the picture, this i could do by add a method in the model 
getTienda1 and return the stock and do it for each store, but i want it to 
be created dinamically because the user could create a new store and it 
will not be there.

so this is my cuestion: can i do that?

(Sorry for my bad english)

combobox prepopulated to only related objects to "self"

[Ignacio Soto]

Hi everyone

i have this model

GROUP and Product


product has a group field thath is foreignkey to GROUP.


and Group has foreignKey to Product to select primary product.

so i want to have a group with many products and one is the "primary 
product".


so...i could do this by select inline products with "trough" and search an 
intermediary Model (boolean field).

but it let me select  more than one promary, 


the solution is the model this way:.

product has a group field thath is foreignkey to GROUP.


and Group has foreignKey to Product to select primary product.

so i want to have a group with many products and one is the "primary 
product".

but the primaryproduct field in group will be prepopulated with only the 
related products to this group.


how i prepopulate the select(combobox) with the reverse query ?

Oops, correction: You'd use user.seller_profile and user.customer_profile if
you've set it up as a OneToOneField -- the get() is unnecessary (and won't
work).

You'd use get() if you used a ForeignKey with unique = True, but that's
silly because a OneToOneField does exactly that but more explicitly.

Re: help plz to install Django

[Ignacio Soto]

Yes kennet is right, the version that is in the repos..maybe is not the
latest release version.

In ubuntu 11.04 is the 1.2 in repos,  you have to follow the install
instructions form the web page djangoproject.

I have a basic profile with information common to both customer and
seller called Person and separate models called customer and seller with
foreign key to person. Thus one person may have multiple roles.
