Re: Absolute beginner question -- recipes

Thank you Rahul,

I actually tried that an this is possible for the relationship between a recipe and its steps. But when it comes to the ingredients for a single step, I cannot do this any more since the ingredients depend on steps again. After reading your suggestion I thought about it once more and I came up with the following solution:

def detail(request, pk):
    recipe = Recipe.objects.get(id=pk)
    steps = Step.objects.filter(recipe_id=pk)

    ingredients = dict()
    for step in steps:
        ingredients[step.id] = StepIngredients.objects.filter(step_id=step.id)

    template = loader.get_template('recipe/rezept_detail.html')
    context = {
        'recipe': recipe,
        'steps': steps,
        'ingredients': ingredients
    }
    return HttpResponse(template.render(context, request))

However, when it comes to the view, it does not work any more:

<h1>{{ recipe.name }}</h1>

<table>
{% for step in steps %}

  <tr>
    <td>
    {% for ingredient in ingredients.step.id %}
      {{ ingredient.amount }}
    {% endfor %}
    </td>

    <td>{{ step.description }}</td>
  </tr>

{% endfor %}
</table>

According to what I found on google, the django template language cannot deal with accessing dictionary entries using variables as keys. What is the django-way of solving this problem? Any ideas?

Thank you!
