Export templates and query fields

[Aaron Street]

Hi, 

In the Documents is says 

Export templates are written in Django's template language, which is very similar to Jinja2. The list of objects returned from the database is stored in the queryset variable, which you'll typically want to iterate through using a for loop. Object properties can be access by name. 

But how can i output a list of all the possible headers for a particualr type of assest. 

I want to do some thing like below where I am focusing on the device type, but this is not working as I assume I am not using the right name for the primary IP? 

{% for device in queryset %}

{{ device.name }}  {{ device.primary-ipv4 }}

{% endfor %}

It would be nice in the documents is there was an example to extract all the possible field vlaues that can be used to create and output from. So I can see 

possible values are 

devic.name

device.serialnumber

device.location

..

..

..

Using the API interface I found a lot of these, but still struggling with outputting the custom fields. onj.cf.<name> does not seem to work, might be becasue spaces in the name?

The most direct way to find the available fields and properties is probably to examine the model itself. Each model is defined in models.py under its sub-application. For example, the device model is at dcim.models.Device.

TYo make it clearer 

if i do 

{{ device.name }} ,{{ device.serial }},{{ device.primary_ip }},{{ device.cf }}

I get the output something like 

ASTERISK-SPARE-SERVER-1

KD1K6Y4

None

{'cde-scoped': None

But if i try 

{{ device.name }} ,{{ device.serial }},{{ device.primary_ip }},{{ device.cf.cde-scoped }}

it fails with a rendering error?

You can't have a minus sign in a bareword like that; it will be treated as a subtraction operator.

It will need to be changed to something like:  {{ device.cf["cde-scoped"] }}

(untested, but if that doesn't work, look through the django templating documentation to find a way to do attribute accesses)

Or you could change your custom field to use an underscore rather than a minus.
