Django: TypeError: int() argument must be a string, a bytes-like object or a number, not
<p>Please help! I tried searching for an answer, but I think this issue is too specific to have a generalized enough solution. </p>

<p>It's very difficult for me to pin point when, exactly, it is that this error started. I've Attempted too many changes now to know when the site was last working. I'm very new to this. And entirely self-taught, at that. I can assure you, it will be apparent.</p>

<p>when attempting to migrate I receive this error:</p>

<p>Problem solved, thanks to @MosesKoledoye. </p>

<p>I deleted the migrations folder inside the app that was causing the problem. And recreated it by running '<code>python manage.py makemigrations &lt;appname&gt;</code>' I then migrated to the server, and everything was great. </p>

<p>Thank you, @MosesKoledoye</p>
