[FORMS] Force participants to answer all items

  In the meantime, I found this post , which adresses almost exactly what I'm trying to do, even though I still struggle to implement it.

  Two differences: I'm not using a multiple choice but a base form item (doubtful that this makes a difference, though). And I want more than one item per page, and I have no idea how the if-check has to look like.

  The example code I'm trying to incorporate is this:

  while True:
      # Prepare and run the multiple choice forms (you'll have to adapt the names to your own experiment):
      items.prepare("form_multiple_choice")
      items.run("form_multiple_choice")
  
      # If no response is given, continue to show the form.
      # Otherwise, break from this while loop and advance to the next item
      if var.response != "no":
          break

  So, another couple hours in, I realize that there's a new function implemented for that. I just don't get it to work, though, I can't make sense of the manual. I tried pasting this into my forms but whenever I run it and come back to my form, it all has vanished again. Where do I have to put it, how can I pass functions to my forms?

  Is there a MWE of the form validator I could use to get the drift? I'm at a bit of a loss...

  Hi Vincent,

  To use form validation, you need to implement your form using Python code, as described here:

  • http://osdoc.cogsci.nl/3.2/manual/forms/custom/#creating-forms-using-python-inline-script

  It sounds like you've implemented your form with a form_base plugin, and tried to insert the Python code there (which doesn't work). Is that right?

  If so, I would first try to recreate your form in a Python inline_script. Once you've done that, adding the validation is relatively straightforward.

  Cheers!

  Sebastiaan! Hooray!
  Yes, that was absolutely correct, and I will try out the inline scripting later today. Thank you so much!

  Like. A. Charm. You're the best, thank you so much.
  One more thing: how do I go about formatting the form screen with inline script? I used the "_theme grey" color scheme earlier, which looked nice, and now it's all looking rather dull.

  Hi Vincent,

  form = Form(theme=u'plain') is the inline command to change the theme. To my knowledge, there are currently only two themes -- gray and plain.

  Hope this helps,

  Hey Eduard,
  thank you very much for your reply. I've found that option, but what I don't understand is: when I build the questionnaire with the built-in form blocks, it was black font on white background (with the theme gray), when I call this same theme when building the questionnaire with python inline scripting, it's white font on black background. It's not a big issue, I can well use it that way, I'm just curious as to why is that and how could I change it.
  All the best to you guys
  Vincent

  Hi Vincent,

  In the general information section of your experiment (first or second item in the overview area), you can set the background and foreground color. I think setting the colors will also show in your form (but not sure).

  Eduard! Thank you so much, again.
  Sometimes I get a bit embarrassed about what basic kind of questions I bug you guys with, I'm sorry.
  Thank you so much for your support!
