            I want to append the filter in rust diesel diesel = { version = "1.4.7", features = ["postgres","64-column-tables","chrono"] } and tried to do like this(if this works, I could add the conditional query for the diesel query):

            Without more detail information, I guessing you want to do condition query with diesel. For example, if your request contains condition named company, You can tried to append the filter like this way:

            Unable to remove empty space in Pandas + Gibberish output in CSV
            Asked 2022-Mar-09 at 05:38

            I extracted some information from a HTML table, reorganized the data and tried to output the data to a CSV file. However, I'm seeing a lot of gibberish in the 'price' column of the output CSV (see below). When I check the dataframe contents within Python, I see that the price column seems to have empty spaces/tabs and weird alignments.

            Results when I print out the dataframe:

            Add this line, after all your existing apply/replace lines. After this, it prints fine. Looks like you have unicode characters, which can be encoded to ascii and ignore errors:

            Answered 2022-Feb-12 at 21:17

            You can start by creating a dictionary for each record and then group by category to create the final dictionary format desired.

            TL;DR - the best solution is in the end.

            The most straightforward way would be to go over your data and append rows one by one:

            Asked 2022-Jan-25 at 05:15

            I'm trying to get the diesel crate to work with SQLite but going off the getting started guide, it does not seem to work for sqlite.

            The code which does work with postgres but not sqlite



            Answered 2022-Jan-25 at 05:15

            Using execute rather than get_results works for SQLite. This will not return the result of the query though so a second query will have to be run to get the updated values.

            As said in the comments, Conn can not be shared between threads, so in this case you would need to move the Pool handle, and get a connection from within the clusure itself:
