I would like to use field expansion in my graph api queries and when fetching posts comments etc...
but I would like to get picture from the "from"-field, but I would also like to get the category field so I can know if it's page or user.
If I don't use field expansion I get the category, but not image. but using field expansion I get picture but not category.
e.g
/me/home?fields=from
returns {id: 1, name :"x", category : "y" }
but using it like this:
/me/home/?fields=from.fields(id, name, category, picture) returns null,
if i remove category it works ok.
So is there a way I can get the category + picture for that field, or is there another way to know if it is page or user?

I really struggled to explain my problem and the only way I found it would be possible is - through screenshots as I have a lot of code and I am not sure what is really needed here. So if you want any code, tell me I will add.
The numbers on the pictures indicate the order.
Choosing the category
Selecting the category it redirects me to - /products_list?category=(that category_id)
Filtering through brand in that category
Now please pay attention to the URL and what happens after I have chosen the brand I want to filter with.
Back on the first page
Problem is here:
Now I am back on the first page, where are all the products but I wanted it to stay on that URL where are that kind of category products.
What I wanted to happen? Instead of it taking me to the page where are ALL the products and then doing the filtering, I want it to stay on that category page and return the filtered products there.
The brand dropdown menu also should only show that category products that I am in, not all.
You need to pass the other parameters as well. So that means that for two parameters category_id and brand, you create a URL that looks like:
{% url 'product-list' %}?category={{ category_id|urlencode }}&brand={{ brand|urlencode }}
If you thus already filtered the category down, you pass the category_id to the template, and render the URLs with the ?category={{ category_id|urlencode }} part.
After trying for hours, I am coming here. I have the following model:
class Items(models.Model):
date=models.DateField()
giver=models.IntegerField()
Class Givers(models.Model):
name=models.CharField(max_length=25)
Basically, an item could be given by donators from Givers model or it could be bought by user. If given, giver field stores id from Givers model. Else, it is 0. Now I want a query that will list out my items. If giver>0, I need to show the name of the giver. I can't create relationships here. This query has brought me so close and works like a charm on literal values but I want to provide the 'giver' field instead:
data=Items.objects.all().extra(select={'giver_name':giver_name(1,False)}).values('giver_name','id','date')
It works like a charm even if given any number (exists or not exists). But I want to do something like this but it fails cos field is not found or undefined:
data=Items.objects.all().extra(select={'giver_name':giver_name(giver,False)}).values('giver_name','id','date')
giver_name is a function that accepts id of a giver and a boolean value and returns a name.
So I am pretty new to Sitecore, and I seem to have gotten myself into an issue that I cant solve or google ;)
So I have an item, this Item has a treelist, and that treelist has a datasource "Products". Now this works fine, the issue is that I only want the items (products) displayed in my treelist, where the Product Category is "Shoes".
The Product template has a Multilist named "Categories", so i would like a query, that evaluated if one of the Categories is "Shoes" if so, include the Product in my Treelist, if not exclude it.
Can it be done with a query or do I need to do some actual code to get that result?
Any help would be much appriciated.
You can use Sitecore's fast query in source field of template field as below:
Using contains:
fast:/sitecore/content/Home/Products//*[contains(#Categories = 'IdOfShoesItem')]
Using like:
fast:/sitecore/content/Home/Products//*[#Categories = '%IdOfShoesItem%']
On older sitecore version fast query does not work, in those cases replace "fast" with "query" like below:
query:/sitecore/content/Home/Products//*[#Categories = '%IdOfShoesItem%']
am Using Apex4.1,
in my application I have one Tabular form which has the following fields,
Emp_id
Emp_name
Dept_id
Here Emp_id is the Updatable column and it is a select list LOV and
Emp_name is a upadatable column,
Here what I need is,
If I select the Emp_id from the LOV ,the Emp_Name should be stored automatically based
on the value selected in EMP_ID,
In tabular form I could not create Dynamic action like creating in normal forms,
Can anyone help me in this issue?
Thank you.
APEX does not currently provide dynamic actions on tabular form items. Hopefully this may be addressed in APEX 4.2 but the Statement of Direction does not explicitly say so.
So for now if you need to do this you will have to write your own Javascript, using the unique IDs of the tabular form items to manipulate them (the IDs look like "fcc_rrrr" where "cc" is the column number and "rrrr" is the row number). See this SO q&q for sample Javascript code that uses these.
The Javascript you need to write is a little daunting (for a beginner), but one thing to note is that in your case you can avoid any need for using AJAX to get the employee name by embedding the name in the return value of the LOV something like this:
select emp_name d, emp_id||':'||emp_name r
from employee
order by 1
This way the return values will look like '123:John Smith'; your Javascript can parse this string and extract 'John Smith' and insert it into the emp_name item on the same row. Obviously you will also need to parse this string to obtain the emp_id value you will need when updating the database when the page is submitted.
I normally use something like this "Tag.object.annotate(num_post=Count('post')).filter(num_post__gt=2)" to get tags with more than 2 posts. I want to get number of posts with a field value (e.g post.published=True) and annote over them so that I get tags with number of published posts bigger than some value. How would I do that?
Edit:
What I want is not filter over annotated objects. What I want is something like this: Tag.objects.annotate(num_post=Count("posts that have published field set to true!")). What I am trying to learn is, how to put post that have published field set to true in Count function.
You can just replace the 2 in ..._gt=2 with some other variable - for example, a variable that gets passed into the view, or a request.GET value, or similar.
Is that what you're trying to do?
