QUESTION
Hello All! I am trying to implement a cart for a simple website that fetches from an API. So my render method looks something like this...
...ANSWER

is just a value representing the total value in the cart. It's not a function from what I can tell.
You can see by the state interface it's a number:
QUESTION
This is a continuation of a thread I started in a past here
After some time I'm coming back with kind of similar question, but this time would like to get the full understanding on the problem to get it solved finally.
Let's say I use the following Power BI data model:
Based on the model, I have build the following report:
As you can see, on the visual I combine attributes from ProductCategory and Product tables. I'm also adding a measure, here named [Some Measure], that is defined like:
...ANSWER
Answered 2021-Jan-20 at 13:26I'm afraid that the problem is that you have a snowflake schema. Therefore the SUMMARIZECOLUMNS
in the client generated query that calls the measure doesn't trigger the auto-exist, and the result is the equivalent of CROSSJOIN on the fields of the Product and ProductCategory tables, followed by a filter on the result of the measure being blank. This explains why you are seeing the cartesian product of the two fields.
The best solution to avoid this kind of problems is to merge the ProductCategory table into the Product table to have a Star Schema instead of a Snowflake. This way your query will trigger the auto-exists and only existing combinations of the columns will be used.
If it's not possible to change the snowflake schema to a star schema, then the measure should be modified to return blank when the combination of fields generated by SUMMARIZECOLUMS
(behaving like CROSSJOIN
) do not exist. I think that ISEMPTY
might be used to perform this test.
QUESTION
Hello I am making a animation time series map in CARTO builder. The animation works fine, but I would like my points to continuously move from point A to B, not just populate from point A to B like its doing now if theres a vast distance for the particular ID for that point. I know this would work if I had many more coordinates filling in from point A to B like in this example, but I don't. So is there a way to do this in cartodb?
...ANSWER
Answered 2017-May-22 at 14:32CARTO BUILDER allows you to analyze and visualize your data according to your values. So as you pointed out, you would need to enrich your dataset with data among those dates and locations. Regarding dates, you can use generate_series
PostgreSQL function as explained here. In relation to generating points between two coordinates, you would need to create a line (via Connect with lines
analysis or ST_MakeLine
) and then apply ST_DumpPoints
).
