Filters are used to process and filter data, stored on the platform, to make it available anywhere via hashtags mechanism. It is a visual way to create SQL requests to data stored on the platform. 


FILTERS' USAGE

Data sets that can be filtered

How to refer to filtered results

Where to reference Filtered data

  • in any Constructor Elements/Components
  • in Events creation hashtag as value
  • To define elements visibility logic
  • Loops for multiline/element data
  • Operations


This is how a set of Filters can look in you app:




You can create Filters in APP DATA section for both Objects and Events (ORANGE MARK) , Add New Filter (RED MARK).



Demonstrares how to hide and show filters for Events and Objects on Mobsted multichannel PWA platform

You can make VISIBLE/INVISIBLE or HIDE/SHOW needed filters in your admin panels ↑




Each Filter shows:

  1. Aggregate function chosen - SUM, AVG, MIN, MAX, COUNT
  2. Number of records fitting the conditions
  3. When it was last time refreshed



Setting up an Events/Objects Filter


Create and Name a new Filter. Naing is very important, as you will refer to it's data using Hashtags:


Set up Events/Objects Filter's Conditions:


  1. Select the value to be compared. Possible options:

    • Action name of the Event

    • Key of the Event

    • Object property, such as: Phone, Email, Login date.

  2. Select the comparison criteria. Possible options:

    • Equal ( = ) - strict match.

    • Not equal ( <> )

    • Contains

    • Doesn't contain

    • Is Set - checks if the field specified is NOT empty

    • Is Not Set - checks if the field specified is empty

  3. Select the comparison value. Possible options:

    • String from the dropdown

    • Any text typed in manually


Filters automatically pull data which you have in any of your tables. So, for example, if you have a Column called Email in Objects, then you'd be able to select it for checking.

SO - Make sure all data fields you need in filters are ALREADY CREATED.



EXAMPLE 1Set up for Object filter that calculates the average age of people with mobsted.com email:





EXAMPLE 2Set up for Event filter that calculates the number of clicks on the button with the BackendName "updatePhone" within 7 days:





Merge Results of Two Filters


Each Filter can ONLY contain either AND or OR condition. In order to have OR + AND conditions use server side hashtags within new filter.


EXAMPLE: we created the filter that will display everyone with email on Mobsted OR Outlook domain, and who has US phone number.





  1. First filter will contain the required Email condition, we will name it as Email.


2. Second filter will contain the required phone condition merged (AND operator) with the Email filter above.



You need to use this hashtag to render filter's results in server side and pull it into second filter's conditions - #ServerSide:ObjectsFilter:NAME:[email protected](",", "[email protected]id")#

 Where two variable are:  NAME - is how you call the FIRST filter,  ID is a common field used to JOIN results with. 




USE PERIOD SETTING

Set up a time period the filter will be applied on. Time period can be fixed between dates specified, or dynamic - older than 2 days / younger than 3 weeks. Can be used with OR or AND conditions, but not combined.The example of setting up fixed on dynamic time period in Filters on Mobsted multichannel PWA making platform



PREVIEW YOUR FILTER RESULTS

Click on the filter to see all the data applicable to it. To see all the data click again on the filter to unselect it.

Use Filter Results on App Screen


It is possible to display filter results to app user by using Hashtags.




SHOWING SINGLE FILTER RESULT

Showing filter counts: We use Hashtags to refer to Object's Filter "Age" and show the Count of matching records - #ObjectsFilter:Age:Count#



To see how it is set up go to the Demo App in your account, screen name - "Filters Count".




SHOWING AN ARRAY OF FILTER RESULTS

Iterating through filter records: We use Hashtags functionality combined with loops to go through each record. How to set it up:

  1. Enable loop on the element you want to iterate

  2. Use your filter data as data source. In our case it is #ObjectsFilter:AgeEmail:Data#

  3. Name the loop. In our case it is AgeEmailLoop

  4. Reference the loop and call the properties of the Object that you want to display, in our case it is Name ( #Loop:AgeEmailLoop:[email protected]# ) and Age ( #Loop:AgeEmailLoop:[email protected]#).



AND Resulting view in app:



To see how it is set up go to the Demo App in your account, screen name - "Filters Iterate". Also Refer to Loops article on details of looping arrays of data. 




Filtering Lists of Data Tables

This functionality is not yet visually shown (like in Objects/Events. However it is 100% up and running on a backend of Mobsted. Write to [email protected] and we will create any number of Filters needed for you - it is free of charge
