I am trying to write a multi-page app. I would like for the home page to be a form for the user to fill out, the callback to query
table1 in our database for that information and return a list of results, and then pass the list to
/page-1 where a list of results will be displayed (plus a radio button next to each). Then the user clicks one of the radio buttons, the callback queries
table2 of the database and returns a dataframe, and passes the dataframe to
page-2 where it is graphed. Here’s a visual if that makes it clearer:
Home Page Layout 4 input boxes with lables Submit button Callback Input values from input boxes, n_clicks Output list object Function to query database.table1 for all instances of the 4 inputs return ResultsList Page1 Layout Radio Button with Label for each item in ResultsList Select button Callback Input RadioItems value, n_clicks Output dataframe Function to query database.table2 for all instances of input return dfMyResults Page2 Layout Graph of dfMyResults
I’m afraid if I have all of these items on one page, it will fill up and get to busy. Is there a way for a callback to hide an element?
I don’t want to have plotly read a csv file because our database currently has several hundreds of thousands of rows and is growing weekly. The csv file would be huge and difficult to keep up to date. I don’t know if a json file would be any better for the same reasons.
I haven’t had any luck with Google searches, so I’m reaching out here. Any help is appreciated. Please let me know if I need to clarify anything.
