Can't iterate over nestled dict in django

Im trying to iterate over a nestled dict list. The first level works fine. But the second level is treated like a string not dict.

In my template I have this:

{% for product in Products %}
<li>
    <p>{{ product }}</p>
    {% for partType in product.parts %}
        <p>{{ partType }}</p>
        {% for part in partType %}
            <p>{{ part }}</p>
        {% endfor %}
    {% endfor %}
</li>
{% endfor %}

It's the {{ part }} that just list 1 char at the time based on partType. And it seams that it's treated like a string. I can however via dot notation reach all dict but not with a for loop. The current output looks like this:

    Color    
C    
o    
l    
o    
r    
Style    
S
.....

The Products object looks like this in the log:

[{'product': <models.Products.Product object at 0x1076ac9d0>, 'parts': {u'Color': {'default': u'Red', 'optional': [u'Red', u'Blue']}, u'Style': {'default': u'Nice', 'optional': [u'Nice']}, u'Size': {'default': u'8', 'optional': [u'8', u'8.5']}}}]

What I trying to do is to pair together a dict/list for a product from a number of different SQL queries.

The web handler looks like this:

typeData = Products.ProductPartTypes.all()
    productData = Products.Product.all()
    langCode = 'en'
    productList = []

    for product in productData:
        typeDict = {}
        productDict = {}
        for type in typeData:
            typeDict[type.typeId] = { 'default' : '', 'optional' : [] }

        productDict['product'] = product
        productDict['parts'] = typeDict

        defaultPartsData = Products.ProductParts.gql('WHERE __key__ IN :key', key = product.defaultParts)
        optionalPartsData = Products.ProductParts.gql('WHERE __key__ IN :key', key = product.optionalParts)

        for defaultPart in defaultPartsData:
            label = Products.ProductPartLabels.gql('WHERE __key__ IN :ke开发者_运维百科y AND partLangCode = :langCode', key = defaultPart.partLabelList, langCode = langCode).get()
            productDict['parts'][defaultPart.type.typeId]['default'] = label.partLangLabel

        for optionalPart in optionalPartsData:
            label = Products.ProductPartLabels.gql('WHERE __key__ IN :key AND partLangCode = :langCode', key = optionalPart.partLabelList, langCode = langCode).get()
            productDict['parts'][optionalPart.type.typeId]['optional'].append(label.partLangLabel)

        productList.append(productDict)    

    logging.info(productList)
    templateData = { 'Languages' : Settings.Languges.all().order('langCode'), 'ProductPartTypes' : typeData, 'Products' : productList }

I've tried making the dict in a number of different ways. Like first making a list, then a dict, used tulpes anything I could think of.

Any help is welcome!

Bouns: If someone have an other approach to the SQL quires, that is more then welcome. I feel that it kinda stupid to run that amount of quires. What is happening that each product part has a different label base on langCode.

Iterating over a dict yields the keys. You want either the iteritems() or itervalues() method.

{% for partName, partType in product.parts.iteritems %}
    <p>{{ partName }}</p>
    {% for part in partType %}
        <p>{{ part }}</p>
    {% endfor %}
  ....
