Is it possible to create models inside a database model

[aditya]

I have created a model Named Gallery and set upload path to media folder and in that folder I have 15 more folders with different images.
Now I want to access each folder and images present inside it using database.
My question is :
Is it possible to create 15 model inside an model and if possible, then How to access them in my Html file? If not then what should I do to show them in my Html file ?

Good question - I'm looking for a similar solution myself. My application is a purchase order app so that a purchase order has details about the purchase order but also has an unspecified number of objects that belong to it (purchase items).

The only way I can think this MIGHT work is making a model for each, including a foreignKey to relate the puchase items back to the purchase order, and possibly putting both in the same CreateView/DetailView/UpdateView/etc. (if this is possible). I'll keep you updated if I find any better solutions though

Also- this is assuming you're using CBVs, if youre just using FBVs its probably even easier on the view side, the model side would be the same

I am using CBVs in model.py file and FBVs in views.py file.

Oh ok I see. The related_name is what you use to access the specific field in the template so it needs to be unique to the model field. When you use the ForeignKey field type it uses the primaryKey of the related database models automatically so you dont need to worry about actually telling it which field to use to relate to in a RDBMS sense.

Well I was thinking is that instead of using related_name is there any other way I can write and call my images inside css lightbox for the slide show.

for alexander .. you can make three models .. one for orders .. one for items .. and one for orderedItems .. the orderedItems model will have relations to  both models items and  orders

you cant make models inside models becouse you cant make tables inside tables ... a model is a database table

 

aditya the easiest way is to redesign your model and make it of 15 fields ..each field will upload to a specific folder inside the media folder 

another way . is to make a one image field and another char field . and pass a choices to it . the choices will be a tuple with subfolder name inside media folder . the make the path inside the image field dynamic comming from that tuple of choices .. 

i didn't make something similar but you can give it a try
