QUESTION
I'm trying to filter the users input through a list of products.
When the user erases their input, I'm trying to implement a filter tracker to see if the user did that, so that the array updates accordingly.
I don't know what's wrong with my logic but I can't get the returned filtered value to render, instead, I get the initial state value.

I know this error is very common in this community, however I'm left dumbfounded at something so stupid. when I try to connect mapState and mapDispatch and finish my redux hard boiled code I get a typeError when I try to fetch the state to be used as props in my component

...ANSWER
Answered 2021-May-06 at 10:17First you are importing App from ./App. You need to import from ./AppWrapper.
Second, you don't pass initialState in the reducer so the state doesn't have the initial value so this error occurs. You just need add initialState in reducer like this:

QUESTION
I modified the code given by @Alan Wells in Find position of a cell containing a specific string but I don't know why it still inserts the matched string into the next empty cell. It supposed to only insert IF no match found in the entire data range declared in values array. Please help to modify my code below. Thanks.
...ANSWER
Answered 2020-Oct-14 at 12:10break expression within the switch statement only breaks out of the switch, not of the for loops
Thus, even after successfuly finding a name (in one cell), the function will keep looping through the other cells and insert the name in all cells where it is not contained.
- What you need to do is to introduce a global boolean that reflects the status of finding the name
- Once the name is found - set the boolean to
true - Check at the end of each inner loop iteration either the boolean is
true - Once it's
true(the name has been found) - break out of theforloops - After the exiting the
forloops without finding the value - go ahead with inserting the value - The code block setting the value will not be run, if the value has been found in the sheet, and thus the function has been exited before finishing the full iteration

I am working with Clarifai's API to write the returned responses to a CSV. For each image I submit, I want to take the top 5 images and append their metadata to a row in a data frame with the file_id as the first column. So each image would have 5 rows with the metadata attached to it in each successive columns. I seem to be generating some dictionary entries where the order of the values in the list being appended isn't preserved and I am trying to figure out why. This is a sample response I am iterating over.
...ANSWER
Answered 2020-Sep-28 at 14:36This is for posterity. The new Clarifai GRPC client has different data structuring. So as a result, I had to parse them by first listing fields. This is what my final loop looked like. It had the ListFields added line

I am trying to use the SQLAlchemy-ImageAttach with Pydantic and FastAPI, but not having much success.
I have never used SQLAlchemy-ImageAttach before, and I am sure I am using it wrong. I cannot seem to save any images, but I can get all non-image aspects working. (I have successfully integrated SQLAlchemy + Pydantic + FastAPI, and there are also great examples to help.)
I am trying to make a DB-backed website where users can create quiz questions and embed images along with the questions, too. The code below highlights the portions related to the quiz questions + images.

...ANSWER
Answered 2020-Aug-07 at 16:07SQLAlchemy-ImageAttach uses lazy=dynamic parameter by default when creating a relationship: https://github.com/dahlia/sqlalchemy-imageattach/blob/master/sqlalchemy_imageattach/entity.py#L148. So question.pictures returns a Query object instead of a list and you need to call question.pictures.all() to get the list of pictures.
You can set lazy=select or lazy=joined. See more about lazy param here.
