formu | A form-building website in the style of wufoo | Form library

In order to create forms out of models you need to use ModelForm not Form. Otherwise you end up with a regular form without any field.

I had the same problem and installing an older version of glmnet fixed it.

Try this:

You are controller is inheriting from ApiController, but your route are configured for a MVC controller.

1. If you want to use ApiController then configure route using .MapHttpRoute method.
2. If you want to configure using .MapRoute method then inherit you controller from Controller instead of ApiController.

Also, in your url you are adding /api after your host and port. The /api is defined in routeTemplate when defining your route using .MapHttpRoute as below -

hi
My goal is to find a way to control the start and end date, after a little research I found a solution but with jquery and jquery-ui technology (user interface) so i add these CDN link in the :

If I understand correctly, you want to calculate the difference between a given row and the row before.

If the rows are in chronological order, you could use .diff() method after grouping by id.

There are a lot of missing closing tags after . This is breaking your document structure. Inserting at the end of the loop should fix this.

In addition, each modal has the same id mymodal inside the loop (this is also the case for your forms, which all have the same id insert_form). This might lead to some problems with the bootstrap JavaScript, because there is no unique modal for each button in the tables. You should make sure, that each id is used only once for the page. You can insert counter and create unique ids like mymodal-1, mymodal-2... to avoid this.

When your object does not finds an image it returns error, so you can add this it will check if model object has image or not. If it does not it will simple not execute ever.

I think this code is slow because of how often it touches the worksheet. There are both read and writes to worksheets in loops. There is also a recursive function that writes to the worksheet in a loop. I can't tell if you are doing this for ease of use or because you need to display the output. Avoid writing to the worksheet until output is required. Output all the data at once, instead of one cell at a time. See the example I give in the Sequence procedure.

I made the code have fully defined references so the system has to do less guessing and lookups. I doubt the performance change will be drastic.

R and DT count columns differently. In R the leftmost column is column 1. In DT the leftmost column is column 0. This is also known as one or zero-based array indexing.

Adding a few strategic +1 or -1 will do the trick.

If you need help knowing where to put those, feel free to post a minimal example and we can help you work through it.
