Gridview with CRUD Options (MySQL)


#1

Hi,

I'm creating a grid view with CRUD options using MySQL. The following link consists of the example:

https://flows.nodered.org/flow/e32f2b942bce77ef6079c0642b93c036

I had tried a part of it here and I'm unable to display the data. In short, the page went blank. Debug node showing all the data in JSON format.

The following is the flow:

Questions about Braces Syntax Usage in Mustache Template
#2

I suggest you start by looking at the page using chrome and viewing the console to see if there are any errors.
You might add some debug nodes and a catch node to your flow


#3

All mainstream browsers have good developer views. F12 is usually the quick way to activate them.

I would also add another debug node onto the output of the web template node, that way you can see what (if anything) it is producing.


#4

That is a nice little GridView example -- I just had to make a few small tweaks to the Web Template node to get it to display properly:

    </section>

</html>

I'm not sure what is supposed to happen when trying to save changes to the data, but you probably already have the /update endpoint somewhere else in your flows. When you get it all working, please update and document it in the flows library -- I know others have searched for similar solutions in the past.

This is what I got:

I would like to do the same for insert, update and delete. The following is the flow:

Your HTML output from the template node is too long to see all of it. You should save it to a file or increase the size of the debug output temporarily (in settings.js) or maybe temporarily delete all the < head > parts so that you can actually see the grid.


#8

Hi,

I somehow managed to insert, update and delete the data from the Gridview, but I'm stuck at search function.

Hope to hear from you soon. Thanks for helping.


#9

Hi,

Currently I'm stuck at search function. I also would like to insert and update data shown in the following link:
http://js-grid.com/demos/data-manipulation.html

How to do this in Node-RED?

Thanks for helping.


#10

Hi all,

Is anyone there to help? Thanks for helping.


#11

Providing your flow would be helpful


#12

Hi,

I'm now able to perform CRUD operations. However, I'm unable to display the data and perform CRUD operations with dropdown fields.

I'm only seeing a blank page with "Machine Management" heading once I changed two fields type from "text" to "select". If I set the fields type to "text" back and remove other dropdown properties, everything is working perfectly.

The following is the flow:

Here is the code:

Thanks for helping.


#13

And in which node are you making that change?


#14

Template node


#15

Please provide the code that created the database and a sample of the data


#16

The following link consists of an example which meet my requirement. In the example, country names are being displayed on Country column. When click on any row, Country column field of the row will become dropdown (with options from another table of the database) and we are able to perform CRUD.

For example, I have country table with id and country columns. I only would like to add/edit id of country table on country column of machine2 table.

Link: http://js-grid.com/demos/basic.html


#17

That is a great demo of the front end, but doesn't answer my request. If you want help you have to provide the date. I'm not going to spend the time creating the SQL to create the tables and load that data, it is not worth my time to do that.

If you provide it so I can create the database and tables YOU use to help YOU figure out an issue YOU have, I'll be happy to spend a little of MY time helping you. But if You don't want to do the work to provide the data needed to debug YOUR issue, why should I or anyone else?


#18

Hi,

I had uploaded the the sample data here. Thanks for helping.

queries.txt (725 Bytes)
Sample Data (tab delimited).txt (2.0 KB)


#19

The sql and data (not in a format that will allow someont to load it into a database!!) do not match the table you are using in your queries.

To move forward with helping you, you have two choices:
(1) provide the sql that will create the table and load the data you are using in your flow
or
(2) change your flow to use the table you just created


#20

Hi,

I had created a demo flow for this issue. The following is the flow:

Expected result: I want lastname field to appear as dropdown (with options Rishan and Login) once I click on add and edit button.
