Hi Runyu, 14.6MB is indeed not a 'too large' study in my humble opinion. JATOS ifself allows study files up to 2GB. But I assume your university's JATOS has some proxy in front of JATOS, e.g., Apache or Nginx, and there the size of uploaded files ca…

Do you get any errors in the browser's console? And can you please post your code here?
-
Hi! I took the liberty to format your code examples and I encourage everyone to do the same - it makes it much more readable. I'm just looking into jsPsych 8 and there seem to be no difference in how to use it together with JATOS. You need three par…
-
Hi! You are using jatos.uploadResultFile and by default the maximum file size per single upload is 30 MB and for all files together within a study run is 50 MB (https://www.jatos.org/JATOS_Configuration.html#result-file-uploading). Since you are upl…

Hi! In general I can't see any problem with your file sizes but I have trouble understanding your question. Can you please provide more info: What is the precise problem your participants encounter. Is there an error message? When does it happen exa…

Hi Jason, I was missing the RewriteCond for the static folder! And the ProxyPass and ProxyPassReverse isn't necessary since we use the RewriteCond. Just for local development, if someone else is interested and for my own reference, I add an Apac…

Interesting. And strange. I'd like to know what causes it. But nice, it's working for you now.
-
I heard this once before but then it couldn't be reproduced. On my laptop it is working. Can you give me more details, everything that might help me reproducing the issue and locate the problem. Which system and browser do you use? Does it happen on…

Hi Christoph! I understand your frustration, but actually JATOS does report an error in this case. To the request that sends result data that are too large JATOS returns with an HTTP status code of 400 and with a response message of "Result dat…

Hi Filip, I turned the Gist into a documentation page: https://www.jatos.org/PsychoPy-and-JATOS.html. I also changed it a bit; now one does not have to edit the JS file but uses the PsychoPy Builder to add the code. Best, Kristian

An user with your username doesn't exist in Mindprobe. However there is a user with drdbruy.debruyne@ugent.be. Best, Kristian

What's your username?
-
Hi Jason, I see since JATOS creates unique URLs each time, so that caching is not possible. That is correct. But JATOS additionally to the file serving does some authorization. Only participants currently running a study are allowed to access the fi…
-
Hi Jason, you can access the jQuery that is loaded by jatos.js with jatos.jQuery. However, it might be removed at some unknown time in the future and you shouldn't rely on its existence in jatos.js for your studies, at least if they should work long…

Hi Filip, I made progress. I managed to turn two of PsychoPy's public demo experiments into JATOS studies. Here there are (if you are interested): https://drive.google.com/file/d/1QRMhBaSYmW8J7578fQ6au59AhqkeWhqS/view?usp=sharing https://drive.googl…

Hi Filip, Unfortunately I've never got an answer from Renato and then never worked on it. Although it shouldn't be too difficult. Let me give it a try with one of the many example studies Pavlovia has. I'll report back here how it went. Best, Kristi…

The admin user is generated for you automatically: https://www.jatos.org/Installation.html. Login with username 'admin' and password 'admin'.

Hi! I had some time to actually try the play.filters.csp.directives in the wild and unfortunately found that it doesn't work with JATOS. Actually play.filters.csp.directives are disabled for certain "publix" endpoints (the ones with 'publ…
-
Seems like you have everything covered. I have nothing to add then be careful with the IDs (but you are already). Best, Kristian
-
Hi Jason, Sorry for taking so long to answer. I needed some free time to understand what are trying to do. I think, I understand your setup with JATOS and one single study containing multiple experiments and the battery.js defining those experiments…
-
Hi Jason, I'm a little bit confused how you are doing the data transfer between the databases. Are you using some shell script with SQL commands? I can't really say what might have caused the issues with apostrophes and HTML tags without knowing mor…
-
Hi Jason! I want to express my deepest concern about changing JATOS database scheme. You might end up with a broken JATOS installation. That said, how do you want to access MySQL from jsPsych? It runs in the browser, isn't it? There is usually no wa…
-
And use '/' and not '\' in your path, e.g. 'img/foo.png'.
-
The upload limit on MIndprobe seems to be 500MB. And I have to correct myself: the proper way to set this in your own JATOS server would not be in the jatos.conf like I said before. In the jatos.conf one can limit only the result data size. The stu…
-
Hi Paz, your .jzip is over 1 GB. That is a lot! Unfortunately we cannot remove the size restrictions on Mindprobe but you can easily do it on your own JATOS installation (it's this config property). You can try to reduce your image size but there I…
-
We had to allow content type sniffing for some study assets to work. Can't remember exactly what it was. But some asset files just wouldn't work with 'nosniff'.
-
Hi! I'm not an expert in CSP directives but I think you got a better approach to allowing iframes than JATOS' documentation has so far. I found this page that explains why it is the better choice. So, yes I agree with you, it is a sane approach. An…
-
Hi Jason, That being said, I, of course, like the approach you strongly advise me against! ;) Your warnings are noted. It's possible, I guess. I've never done it myself. Just a sketch: You have to export/impost the rows of the tables ComponentResult…
-
Hi Paula! I formatted your code to make it better readable. I'd like to encourage everyone to format their code too. First, but maybe you do this already, you can access `jatos.batchSession` only after the jatos.js got initialized. So you have to us…
-
Hi Jason! Sorry for answering so late. I strongly advise against changing JATOS' MySQL via the command line. It's not easy to do and it's likely you break the database. But having JATOS installed on a laptop and do your field experiment this way is …
