Change number of rows shown in datatable in Backpack for Laravel - laravel-backpack

Is there another way to change how many rows are shown in the table other than overwriting the list.blade.php file?


It's a little-known API method, but you can do that by calling this in your EntityCrudController:
$this->crud->setDefaultPageLength(10); // number of rows shown in table view


A lot of time has passed. At the moment with the current version of Backpack (v 4.1.X) there is a setting in the configuration file in config/backpack/crud.php named defaultPageLength that controls the page length globally. If page length for a single CRUD controller should be changed, then $this->crud->setDefaultPageLength(50) is still the way to go.
More details can be found here: https://backpackforlaravel.com/docs/4.1/crud-api#page-length

Highlight a row in list view depending on column value

Using Backpack for Laravel version 4, is there a way to set a css class on a row in list view if a field on the model contains a particular value? I know the ability exists in the DataTables api, but can't think of a way to make it happen in BP4L. Thanks.

How to programmatically create ListView based off SQLite query?

I have some code that allows the user to perform a search by selecting a few checkboxes. A sql query is then created based on what checkboxes are checked. (Up to 5 checkboxes)
The data is then queried against a sqlite data.
The issue is now how do i populate the data into a listview (not knowing how many columns there will be ahead of time (Could be anywhere from 1 to 5)
All the examples I"ve seen is where the listView is created and you know exactly how many colummns are going to be returned.

A previous posted suggested to query all the records and then use if statements to determine if the value is null then hide column.

Google Chart - DataTable inside a form

I have a table created with DataTable of Google Chart, which has a column with a drop-down list. In this way the user can set the proper value of a row.
I am working in Python and Flask and I can retrieve the request data correctly. The problem is that the table, given the amount of data, is showed in pages, each one with 20 rows. When I retrieve the request I get only those 20 rows, so I have no way to know what the user set in the other pages.
How can I get the values of all pages?
Moreover, I noticed that when I change page and then I go back, the table forgets the user changes, so I think I should be careful also to this fact.

Finally, I solved the problem by using a dictionary containing all the changes made to the table and updating the html string inside the table to keep the content updated.

How I can add a row and input field on button click in lotus note 8.5. form?

I have question about Lotus Note. I have form: http://i.stack.imgur.com/YWii6.jpg
In this form I need create bottom. With this buttom user can add new row with input field in this row to existing table. I find that kind of lotusscript from:
http://www-01.ibm.com/support/knowledgecenter/SSVRGU_9.0.1/com.ibm.designer.domino.main.doc/H_EXAMPLES_ADDROW_METHOD_RTTABLE.html
But when I this script copied to this form, I get error "Object variable no set"
Then I tried this solotion:
LotusNotes 8.5 - Adding a row to a table with a button
And I again get the same error.
Can anybody tell me please, how I can create new row and input field in this row, when I pressed buttom "Add row"?

You can't make a table with a dynamic amount of rows in a Lotus Notes Form. There are two common ways to solve this:
Use child-documents; one document for each row; and show these documents using an embedded view. This is the most elegant imho.
Create a large, fixed-elements table, and hide the rows that are not needed (for instance, by checking the presence of an input in the preceding row. This is OK for small amounts of row, but performance starts getting bad if you have too many rows.

It seems you are a bit confused as to the difference between a form (your picture) and a document (the code you link). Also, you definitely need to understand the meaning of "Object variable not set", which is the most common error when you use Lotusscript.
Anyhow, where to go from here depends on how you plan using the data once it is input. Will it be edited ? Will each row need to be handled as a separate record ?

Form visible in Design View, but blank in Form View

My form is showing up in design, but not form view. There are 700+ records.
In Design View -> Data, the Record Source is:
SELECT act.* FROM act;
This query shows all records in Query view.
There are no filters, and Allow Form View is set to Yes.
What is causing my form not to show?
EDIT: I'm noticing that the form is extremely wide. There isn't a width setting, but in Design view with window maximized I have to scroll way over to see the right edge. Would this have anything to do with it?

This link might help you. I remember having this issue and it was because of a read-only query.
Why does my form go completely blank?
Here is an excerpt that lists the main conditions why this could happen:
Condition (a) can be triggered in several ways. Examples:
- The form's Data Entry property is set to Yes. (This means the form shows no existing records, i.e. it is for entering new ones only.)
- The form has a Filter applied (or is opened with a WhereCondition) that yields no records.
- The form is based on a query where the criteria yield no records.
- The form is based on a table that has no records.
Condition (b) can be also be triggered by several things:
- The form's Allow Additions property is set to No.
- The form's Recordset Type property is set to something other than Dynaset.
- The form is based on a read-only query. (If you cannot add a record directly to your query, see Why is my query read-only?)

Auto_title_0 was set to 21" wide. Resizing that to the actual form width solved the problem.

On Design View of the Form click on "Details" which is just below the ruler and make sure that Visible is set to Yes on the Property Sheet.

Try this step.
Click to select Form.
Click on Auto Resize.
Change value to Yes.
Look into this

I also had the issue with a Form I used to input the strings for a query. The problem was that there were no records to answer query as I had changed it to an "Select Distinct" query to get rid of duplicate answers, but it also eliminated new record sets. Deleting the "Distinct" in my SQL solved the problem. Thanks for your help!

For me - the Form.Data Entry property was set to Yes.
Changing it to No shows the form again.

As for my case, I had open two forms.
Form B is link to Form A.
When Form B is opened, Form A is blank because it does not allow for data to be added.
When I close Form B and re-open (or refresh) Form A, the form fields appear.

Hope someone finds this helpful.. I faced this problem and solved by changing Pop On property (under the other tab) to No, and also changing the border style to "Dialog" in design view mode.

I also had this problem which wasted lots of time, but I was able to fix it.
The reason for me was that my target table was empty and I had primary keys set on it and had my controls in my form related to those fields.
So, Access was unable to show blank primary keys and was not displaying the form at all.
If you fill up your target table with some data, save and close the form and open it again the controls will be displayed.
