Thank you Florian. After James pointed out that I can access my steps (and the ingredients in some way) by just passing the recipe object to the templates context, I thought of reducing the view to a DetailView again. But I have to somehow access the ingredients from my template for now ...

The related models using a 'through' table also have access to the 'through' table itself. With your current setup, I think you can do this:

<ul>

{% for steping in step.stepingredient_set.all %}

    <li>{{ steping.amount }} {{ steping.unit }} - {{ steping.ingredient }}</li>

{% empty %}

    <li>No ingredients needed for this step.</li>

{% endfor %}

</ul>

Optionally, for style points (and better human readability of the code), you can also add a 'related_name' parameter to the FK's in the 'through' table:

    step = models.ForeignKey(Step, null=True, related_name='step_ingredients')

    ingredient = models.ForeignKey(Ingredient, null=True, related_name='ingredient_steps')

That way, depending on the direction you are going, the call makes sense to a human:

<ul>

{% for steping in step.step_ingredients.all %}

    <li>{{ steping.amount }} {{ steping.unit }} - {{ steping.ingredient }}</li>

{% empty %}

    <li>No ingredients needed for this step.</li>

{% endfor %}

</ul>

I think that will work, although I haven't exactly tested this.

I'd highly recommend going with DetailView if you can. That makes your view a whopping 2 or 3 lines.
