It's those two letters: fm that make the difference.

The element you searching for only appears after click in dropdown button try to click on the dropdown before click on the option

try this code:

You have to change true to 'true'. The true is a string.

then you need to move the code out to a seperate routine for that row command. In other words, we ASSUME that you have a button OUTSIDE of the grid, say "check" all or whatever.

So, what is the code in the row command supposed to do? Without that information we are all VERY lost.

So, say I have gv, and I want a "check all" box?

Say like this:

Here's one option, which uses

• rank analytic function (to "sort" average salaries in ascending (least) or descending (most) order),
• case expression (to find departments that earns the most or the least) and
• some joins

Based on the error, it looks like the route is passing in "1" as the :uid parameter, but the Mongoose .find() method is trying to coerce it into Mongo's ObjectId type.

By default, the _id key in MongoDB is an ObjectId. ObjectIds are typically a 24 hexadecimal character string (or anything that's 12 bytes), so "1" can't be turned into an ObjectId.

• You could set the _id column to be of type string or number instead of ObjectId manually.
• You could keep the _ids as ObjectId type and modify your code to make sure you're passing in valid ids while searching (--adding pre-validation or an error handling wrapper might be good in that case so that the user gets 400s/404s instead of 500s if something wrong is passed in as a param).

Here's a specific rundown on the difference between how the code might look for an _id that's a string/number vs. an ObjectId type-- the part about ObjectIds is at the bottom: https://masteringjs.io/tutorials/mongoose/find-by-id

Here's some more information general info on MongoDB ObjectIds: https://masteringjs.io/tutorials/mongoose/objectid

Here's some info about the difference between _id and id in case that helps with the way you end up wanting to write your queries: What is the difference between id and _id in mongoose?

Replace the async fragments something like this, assuming they are meant to be executed sequentially.

You can try with 2 merge con the 2 different Titles subsequentely.

For example, let be

• df1 : job_transitions_sample.csv

• df2 : wage_data_sample.csv

  df1.merge(df2, left_on='Title 1', right_on='title',suffixes=('', 'Wage of')).merge(df2, left_on='Title 2', right_on='title',suffixes=('', 'Wage of'))

select distinct SupervisorENO from EMPLOYEE will also return NULL, any any value when compared to NULL will not actually return True or False, it will return unknown, so to speak. You can read more about that here for example.

So in order to fix your query, you need to exclude NULLs:
