Node-Red: Dashboard UI Table HTML and Link Format
Thank you
how to handle 2 buttons? like if I have button submit and cancel, I want to use switch node to handle
As far as I know, the cancel button just resets the user input and does not output anything. Thus, it is not possible to handle the different actions using a switch because you don't know when the user clicked cancel.
when the mysql node returns error, how to get that error text?
You can use the catch node for that
Very useful, thank you !
You‘re Welcome
Hi, how can i get the name of the uploaded file to save it as that
the filename is stored in msg.file.name
@@ruwindustries thanks
one question : can i show the picture in a nodered dashboard ?
yes you can show the picture in the dashboard using the dashboard template node
well done , thx so much , thats what i was searching for
Glad I could help
nice. thank you
what is msg.enabled? so when you send a boolean payload (converted from msg.enabled) to the button will activate and deactivate it?
Thats correct. If you send “msg.enabled = False” then the user won't be able to use the button.
hi sir, how to download some data using pickdate?
You have to adjust the SQL query to take the date picker into account when selecting data.
thanks for the nice tutorial, For the Delete function , how to make it pop a Confirmation action after user press delete ?
You can use a dashboard notification with user input and only execute the query when the user pressers yes or something
Good video, but please kill the horrible music. It's unnecessary and distracting.
danke, leider furchtbare Musik
Brother, you have an excellent video, thanks for the content you upload. One question, how could I change the color of the animation, of the circle and the background of this with the Level type? Putting a name in the properties didn't work for me, so I changed the letters to the general class that each gauge has.
what is the password? 1:51
The password you set when creating the database.
the best mysql database tutorial 👍
Thank you 🙂
thank you, so clear and precise video :)
Your welcome
how do you set the format to MM/DD/YYYY instead of that crazy day first format?
Te amo, gracias
Thank you for your videos. They have been very helpful so far. Is it possible to only receive the value of the cell the user clicked on?
Hi, thank you for watching them - I really appreciate it. There is probably a solution when using tabulator callbacks. Specifically, the cellClick Callback found here: tabulator.info/examples/4.4 However, I have never used those for my tables, so I don't know how to use them.
Hello, i am newbie in node-red, how to change color button if i clicked it?
You can set the Background Property of the Button to {{msg.color}} and then inject "green" in msg.color after you clicked the button. The string has to be a html color name. htmlcolorcodes.com/color-names/. If you need more help, please join the discord sever. There I can also send you some example code.
Se volessi leggere lo stato dei contatti delle finestre direttamente dai gpio che accorgimenti dovrei prendere per evitare di danneggiarli? Come comune vorrei usare il pin 1 3.3v, sono 5 contatti no
You should probably search for Tutorials or Explanations on the internet about using GPIO Pins, as this is not my expertise. There should be enough content about that. Otherwise, you may find someone on the community discord server that can help you out.
Hi, I want to only show text on the dashboard after an input is executed. Ive joined it after my input is (high), but it just remains on the dashboard regardless of the inputs state.
Do you want to show an empty text or remove the entire text field? If you want to show no text just inject an empty string „“.
Hi Sir how can i make this button in the dashboard? the buttons are not buttons they are switches! The button shall go back to zero
In my experience, the normal Dashboard Button works like a button and not like a switch.
@@ruwindustries i managed it! thank u
You‘re Welcome
Thank you for that video: One Question: How can I set a default value für a slider?
As far as I know, you can only set a value by sending it in the msg.payload.
The videos are very useful, but could they be uploaded with explanations included.
Probably not - if you have questions, please join the discord server.
Man u are suuuuuuuppppper
Thank you - I appreciate it
thats a bullshit tutorial. don't do it if yyou don't enjoy it
Hi, can you explain how to use multiple filters? The tabulator documentation use a array of obj but in node red this not work
Hi, I don't know how that works, unfortunately. However, I would personally rather use a database to do the filtering instead of the table.
In the Arduino web server, I want to control LED with API address: port/led on, API address: port/led off, LED control using NodeRed. The node I tried is in IP:port format, so I don't know how to deliver the following.
To use the API you probably have to use the http request node.
@@ruwindustries 팔렛트에서 다운받을수 있나요? 방법을 알려주실수있나요?
The HTTP request is a standard node coming with node-red itself.
Good example , yeah for V2 DB.
Finally a new video... Yes for dashboard v2
Hi, I have ths error "Cannot GET /data/static/files/sensor_values.csv" I don't understand msg.path which does not point to the .nodered folder. An Advice ? Thanks,
The Path /data only works if you use node-red from a docker container. If you run Node Red locally, the part before /static is different. I just use msg.path, so I can specify the path from a function.
@@ruwindustries and what should I change to make it work on my local Node Red?
Hello, why the Date Type input does not work correctly? the date is not match to the local time zone
hello do you know why i got an error even though i adjusted it to your code?
What's the error you are getting?
hallo @RuWindustries do you know how to get the value from the mqtt to the gauge even though it passes through the button?
You can set the value to a different msg property such as msg.mqttValue using a change. If the button doesn’t know the property it will send it through.
Why is it necessary to play music in the background?
It is not necessary - I just like the feel of it, especially for parts without voice over
VERRRRY interesting. thanks a lot
You're welcome
what's the keyboard shortcut to add nodes in the flow like you are doing, just typing it instead of drag and dropping?
I use the Quick-Add dialog. nodered.org/docs/user-guide/editor/workspace/nodes#quick-add-dialog
Is there any way to style the chart lines - make them thinner - just one pixel?
I don't know if that's possible. There is no hint in the docs (github.com/node-red/node-red-dashboard/blob/master/Charts.md). Maybe you can achieve it with custom CSS
This was very helpful! Thank you!! If you know how to make the tabs be across the top instead of on the side I would love to learn that too
I don't know if that's possible - maybe you can achieve it with custom HTML & CSS
great video. i still got some trouble because im trying to get flow variables into the database. could u help me on that?
check out this video: th-cam.com/video/od8Agg9x6sw/w-d-xo.html
Good tutorial. But so far there's only 1 problem on my side. In my csv contain string like value (like device name), while my MySQL database column was created with varchar (255) type. But every time when I tried to insert, in the debug will give error: "Error: Unknown column 'DDC_1' in 'field list'". *DDC_1 here is for the device name column in MySQL. Is there any way to upload string/varchar value via CSV? Thank you for attention.
Seems like your insert command is wrong as DDC_1 should be the value and not the column name
I discovered that if I comment (or remove) the color object in the JSON, the rendering is smooth, without total reloading (perceptible)
I honestly never tried that
Great content, the problem with this approach is that with each message sent, the layout is reloaded, generating a loop in the indicator. Ideally, it would update without reloading all the content.
To better understand what I said, just add an inject with repetition every 1 second and observe the dashboard.
Congratulations, the best content on TH-cam about Node-red!
Thank you very much for your nice words - I appreciate it
Weirdly enough, there isn't a path called "\data\static\files" for me. I am using node-red on a raspberry pi and I am unsure if that's the problem...
You need to create the folders yourself.
Isn't the max_temperature in this case just the temperature? It seems to me like they are always the identical value to eachother.
It is in this case but that does not have to be true in all occasions. flows.nodered.org/node/node-red-contrib-cpu
