title: Show value in table from a model with template in django
body: <p>I want to make a website to manage a bread production but I am facing 2 problems.</p>
  
  <p>I have a model bread (Pain) that allows me to create a bread and to give that bread a starting price.
  (nom_pain = name , prix_HT = price)</p>
  
  <pre><code>class Pain(models.Model):
  nom_pain = models.CharField(max_length=25,primary_key=True)
  prix_HT = models.DecimalField(max_digits=4,decimal_places=2)
  pain_decouverte = models.BooleanField(null=False)
  def __str__(self):
      return '{}'.format(self.nom_pain)
  </code></pre>
  
  <p>I have a model Group (Groupe) that represents different group of clients.
  (nom_groupe = name)</p>
  
  <pre><code>class Groupe(models.Model):
  nom_groupe = models.CharField(max_length=30)
  
  def __str__(self):
      return '{}'.format(self.nom_groupe)
  </code></pre>
  
  <p>I wish to match the price of each bread to a group of clients on one page and then display it in a table chart (inserting the bread prices in the blank cells)</p>
  
  <pre><code>            | Bread 1 | Bread 2 | Bread 3 |
      Group 1 |  0.5    |  0.6    |         |      
      Group 2 |   1     |         |   0.5   |
      Group 3 |  0.5    |  0.4    |   0.7   |
  </code></pre>
  
  <p>My first problem is that I can’t save 2 times a group/bread in my model Price (Prix) (I wanted it in the form of Group / Bread / Price).</p>
  
  <p>The second problem is that I don’t know how to display my table chart in my template. I can only display the breads and the groups of clients available.</p>
  
  <p>Is there a way to do this?</p>
  
  <p>Thank you very much for your answers</p>
