Hi,
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 :key 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.
