MultiValueDictKeyError at /savepost/

Question

I know this has been asked before but I'm facing this MultiValueDictKeyError. Basically I'm trying to take an input from the user, the input tag has this name="usercaption" attribute. While I click on submit it pops up the MultiValueDictKeyError. Here's my HTML form:

<div class="post">
    <form action="/savepost/" method="GET">
        <input type="text" name="usercaption" placeholder="Write Something...">
        <div class="attach">
            <button class="upload-image"><i class="fal fa-image"></i> Image</button>
            <button><i class="fal fa-video"></i> Video</button>
            <button><i class="fal fa-smile-beam"></i> Mood</button>
            <button type="submit">Upload</button>
        </div>
    </form>
</div>

Here's my view function:

def savepost(request):
    caption = request.GET["usercaption"]
    Post = post(caption=caption)
    Post.save()
    return redirect('usersfeed')

The error is on this line caption = request.GET["usercaption"]

You have to provide a default value for if it doesn't exist, so for example:

 caption = request.GET.get["usercaption", ""]

And you have to add the user as well:

user = request.user
Post = post(caption=caption, user=user)

Im still facing the same issue caption = request.GET["usercaption", "Write Something.."] with this code – notVansh Aug 06 '20 at 08:37
You have a `GET` request. You should change it to `request.GET.get` – MeL Aug 06 '20 at 08:39
Now it gets me an Integrity Error when I type this caption = request.GET.get("usercaption", "Write Something..") – notVansh Aug 06 '20 at 08:41
IntegrityError at /savepost/ NOT NULL constraint failed: social_media_app_post.user_id This is what Im facing – notVansh Aug 06 '20 at 08:47
This means that you have to add the user as well. You didn't post your model, so I didn't know. I'll edit my answer – MeL Aug 06 '20 at 08:50
I didn't add any input for user field though – notVansh Aug 06 '20 at 08:53
But the user is in your `Post` model? It means you must add the field, otherwise how will it know to which user to save it to? – MeL Aug 06 '20 at 08:54
oh yeah that makes sense! Thanks man! It just worked! :D – notVansh Aug 06 '20 at 08:55
