I’m trying to learn something about Django, and a doubt has arisen.

I have a dictionary with several keys and valuables. The idea is, for each key, to display a list of values with checkboxes that can be selected to perform other tasks below.

But I don’t understand how I can create models and then correlate keys with values using checkboxes in Django, someone could give me a light?

wouldn’t be the idea?

model py.

class BookModel(models.Model):
  title=models.CharField()

class User(models.Model):
  username=models.CharField()

class Recommend(models.Model):
  user=models.ForeignKey(User)
  book=models.ForeignKey(BookModel)
  friends=models.ManyToManyField(User, related_name="recommended")

html template.

{% for friend in friends %}

<input type="checkbox" name="recommendations" id="option{{friend.id}}" value={{friend.username}} />
<label for="option{{friend.id}}"><b>{{friend.username}}</b></label><br />

{% endfor %}

  • That, that’s the idea, thank you! A question, how could I pass the dictionary so that these templates were filled in? I’m still a little lost in Django and the tutorials are very specific!

  • Hummm, dude, you need to enter the dictionary data using Django’s Orm, using the example q postei would look more or less like user = User(username="name"). save() book = Bookmodel(title="title"). save() Recommend(user=user,book=book). save() #after entering the records, make the query in Recommend.Friends(). values() #Django is complicated to explain, but it becomes simple and quick to create things with it when we get the game

  • Beauty man, thanks for the tips! I’ll try here!

  • let’s say I have the following dictionary of users = {"user1":"user_name1","user2":"user_name2"} dai vc creates a for nesse usuarios like: for key,value in usuarios.items(): and for each input of for vc add in User like this: user = User(username=value) user.save() ...and so on, vc inserts the user into Recommend and ready, then creates a new function in your view to fetch this data with Recommend.Friends(). values()

  • Oh yes, I understood how it works after digging a little! But I was left with another question! If the dictionary is of the type {a:[F1,F2,F3], a2:[F3,F4,F5]...}, how could I save it? I tried using this template but on the admin page I get a column to select a, f, and a relation Many to Many. I wish there was only the attribute and I could relate it to Fs (they are more than one for each attribute!). Actually the doubt is how to relate the "a" with its "Fs" in such a way that in the administration page appear only one column of attributes and another with the relation.
