Create a style that allows to fetch form data from the database and display content depending on a simple condition

In GitLab by @moiri on Jan 16, 2019, 13:42

Using the small library JsonLogic and a new style conditionalContainer content can be rendered depending on whether the specified condition is true.

To refer to a field field_name of a form form_name use the syntax "@form_name#field_name".

The following example would represent one case as explained to me by @olivierbur (the condition is true if (mean(q1, q2, q3) >= mean(q4, q5, q6)) and (mean(q7, q8, q9) >= mean(q10, q11, q12)) and (mean(q7, q8, q9) >= mean(q13, q14, q15)))

{"and":[
  {">=":[
    {"/":[
      {"+":["@survey#q1","@survey#q2","@survey#q3"]},
      3
    ]},
    {"/":[
      {"+":["@survey#q4","@survey#q5","@survey#q6"]},
      3
    ]}
  ]},
  {">=":[
    {"/":[
      {"+":["@survey#q7","@survey#q8","@survey#q9"]},
      3
    ]},
    {"/":[
      {"+":["@survey#q10","@survey#q11","@survey#q12"]},
      3
    ]}
  ]},
  {">=":[
    {"/":[
      {"+":["@survey#q7","@survey#q8","@survey#q9"]},
      3
    ]},
    {"/":[
      {"+":["@survey#q13","@survey#q14","@survey#q15"]},
      3
    ]}
  ]}
]}

It might be interesting to create a nice interface which allows to build such conditions. For the moment we have to do with the rather cryptic json notation as shown above.

Nice thank you! I think it will do for the moment. I will inform you when I created such a condition to see for you if it works. However, it will have to wait a few days.

Great!

I will now work on #116 and once this is done I will create a new version (v0.9.9) and update Hermes if that's ok with you.

That's perfect. Just let me know, so I can Log-out for that time.
