            I'm trying to delete an article with Flask but KeyError appears
            Asked 2021-Jun-10 at 03:01

            Hi I'm coding review page with Flask but struggling with creating delete button. According to my code, when delete button is clicked, KeyError appears. There are only two rows in the review table which are Writer and Content. I pasted showing and deleting review API code, also with Server side Delete function.

            Is my way alright to delete code by sending title and review from client to server then delete the object in DB which matches title and review which is sent by client? I'm wondering why KeyError is appeared. I beg for your help! Thanks for reading.

            The issue stems from your string interpolation when generating the button.

            ${title, review} only injects the value of review. Since your deleteReview only receives one argument, the review_give field in the data of ajax call is left blank, leading to the corresponding missing key in your flask app.

            This is how you correctly do your string interpolation:

            Inserting into a binary search tree in C
            Asked 2021-May-01 at 10:28

            I'm currently learning C and also some datastructures such as binary search trees etc. I have trouble understanding HOW exactly changing pointer values within a function works in some cases and in others doesn't... I'll attach some of my code I wrote. It's an insert function which inserts values in the correct places in the BST (it works as it should). I tried working with pointers to pointers to be able to change values withing a function. Even though it works, im still really confused why it actually does. I don't quite understand why my insert function actually changes the BST even though I only work with local variables (tmp, parent_ptr) in my insert function and I don't really dereference any pointers apart from " tmp = *p2r " in the insert function.

            Thanks for helping out.

            Answered 2021-May-01 at 09:17

            While the pointers themselves are indeed local variables, they point to a specific location in memory. When you dereference the pointer by using the -> symbol, you're basically accessing the memory where that exact variable to which the pointer is pointing to is stored. This is why your changes are reflected outside the function as well.

            You basically told a local variable where your tree is stored, it helped with the insertion, and then it went out of scope. The tree itself is not a local variable so the changes are reflected on it.

            I suggest reading up on how pointers work.

            (str(x) for x in values) is not a list comprehension, it's a generator expression.

            [str(x) for x in values], on the other hand, is a list comprehension.

            The first expression makes a one-time generator that gets exhausted the moment you iterate through it. The second expression places the result of that iteration into a list, so you can access the elements again.

            ANSWER

            Answered 2021-Apr-24 at 15:49

            You have a few misunderstandings here.

            Firstly, as from code, you can see that model is trained on 7 columns as inputs [ip, app, device, os, channel, hour, day]. And the model is trained to predict values from is_attributed column. So feed a model list with 7 values -> receive 1 value as output. And this value seems to be 0 or 1 depends on input 7 values.

            Secondly, we can proceed now to the Flask part. Basically, what you do here is that you load dataframe and select one column (attribute = df['is_attributed']). IF you have dataframe with 50000 rows and you select one column it means that you select 50000 values! And then you tried to send this to model, which wants exactly 7 values as inputs. As from my perspective, it looks like that you want to run model on each row on test dataframe.

            To do that you need:

            1. load test dataframe;
            2. check that you have only 7 columns ([ip, app, device, os, channel, hour, day]) in dataframe. If you have more columns, remove all other;
            3. go through each row in dataframe (each from total of 50000);
            4. run model using 7 values from row as inputs;
            5. model's output append to a python list;
            6. after 50000 runs you will have python list with 50000 values;
            7. return this list.
