Thank you. If you have any questions while building web apps with Dash, let me know.

You're welcome @Fernando. For quicker app deployments to Heroku, try dash-tools. I hope to make a video on this in a few weeks. github.com/andrew-hossack/dash-tools

Thanks Chris. Hope you can become a Charming Data supporter as well.

Charlie, I also made one on PythonAnywhere which is a bit simpler than Heroku and I believe cheaper as well.

I appreciate it Aditya. Thanks for watching

Hi, I tried to use this tutorial to have two pages but since they are not using the same theme one is dark one is white. They don’t work well with each other. Any solution for applying different themes to two pages?

Hi, Charming Data. I am a big fan of you. I want to, how can I share data between multipage dash application. For example i want take dropdown selected data in one page and make a report of that selected option into another page. I have used different callback of each of pages. Thank you if you are willing to help me.

@@bobbuilder2837 Thanks for following me, @Bob. I think you can use the dcc.store component. That should allow you to share data between pages. Google "share data with store dash Plotly forum". I'm sure you'll find many posts on the topic. Good luck and happy holidays

Please update the path to the app files with the new one: Deploy_App_to_Web/Multipage_App

@@UCMENOTx hi @Christian, can you please help me understand what you're referring to? Are you referring to this link: github.com/Coding-with-Adam/Dash-by-Plotly/tree/master/Deploy_App_to_Web/Multipage_App

What do you mean Mohammad?

@@CharmingData i mean, i copied my codes for single page app. I typed app.layout which I had to replace with layout for individual pages.

can you suggest me, where to put junk of codes for user id and password for a multipage app?

Thanks Chuck. Also take a look at the new tutorial video on multipage app I created 3 weeks ago. This makes things a bit easier and should be within Dash version 2.2 soon.

Thanks Chris. I hope you learn a lot

Thank you

Thank you for the support @mikhail2003

Great idea. Thanks Allan

You're welcome @Adrien. Have you built any dashboard apps yet?

@@CharmingData Working on one right now! I started learning Plotly and Dash about three weeks ago. I came into this actually looking to push the boundaries of MatPlotLib, but I stumbled upon one of your videos and was absolutely blown away with the tools this has to offer. It was too powerful not to learn. So here I am now, reading the docs Plotly and Dash has to offer, and then learning how to push the boundaries with your videos! A lot of my current applications currently rely on DiscordPy, communicating over a network. I plan on upgrading all of my programs to use Plotly and Dash, one way or another! I'm grateful you've gotten the attention of Plotly and Dash out there even more. It's made me really happy to be able to learn this tool. Cheers!

@@hghlndr2 That's a nice story of how you've got into Dash. I'm happy you see the potential in it. Good luck with your Dash learning journey.

@@CharmingData Thank you very much!

Thank you Eddie. 😊 In case you'd like to support my way to heaven, www.patreon.com/charmingdata

Hi Richard, No worries. I'm editing the video now. Should be uploaded in about an hour

Hi @Jara, i think that's possible with dcc.Store

You're welcome @stella. Feel free to let me know if you have any questions while building your web apps.

Thanks for watching 🤗

Thank you Julio for your willingness to support this channel. I can't find you on my Patreon. Are you Julio César on my patreon as well or under a different name? Sorry, I can't recognize you from your KZfaq icon 😞

@@CharmingData No problem, my username on Patreon is Alseides.

You're welcome @Hermes . What did you deploy?

I'm working on a school project of data visualisation from IOT sensors, i have 15 days left, really your videos helped me so much to move the project forward !

@@hermesingenui2653 good luck Hermes. If you have any questions, let me know.

Thank you Alec

Thanks Frank Jia

you're welcome Vin.

Hi @Camilo. I use black and like it so far. I haven't tried the other two. I think Plotly uses black as well. Let me know if you choose autopep8 or yapf. I'm curious if they're good too.

Hi Matteo. Have you tried using dcc.store()?

@@CharmingData Yes, but initially I put the dcc.store() in one specific page and it didn't work. Now I put the dcc.store() in the app.layout of the index.py file and it works! Thank you!

@Charming Data, can you please make a video on uploading, downloading and dd.store () in dash

Lograste crear algo lindo con Dash, Iván?

You're welcome @penninah. Good luck with Dash.

Thanks for the suggestion, @Renjie

Hi Dustin, that is on my tutorial ToDo list. I just need more time to make it :) If you'd like to support me in creating the MySQL tutorial and other Dash tutorials, I'd very much appreciate it. www.patreon.com/charmingdata Good luck with your project and thanks for watching my channel 🙏

Dustin, what is the school project youre working on?

Hi Jagriti, Try using dcc.store() dash.plotly.com/dash-core-components/store

Never saw this error, Anuvrat

You can try to connect to an API and upload the information that way. With csv, i usually do it manually

Maybe an individual job using cron? Or task scheduler I use both of these methods and tie it to an email so I Know it runs.

Hi Manuel, I'm going to try to create that tutorial but I have to learn how to do it and make sure I have the resources needed. If you'd like to support these tutorials, I would really appreciate it. www.patreon.com/charmingdata Thanks for watching my channel. Adam

Thanks for notifying everybody, @mikojan85channel

Hi Natalia, yes we're working on a beta version of multipage apps. See my video on multipage app

Thank you

for sure, @khaoula. You can do import dash_bootstrap_components as dbc at the top part of your code.

Hi Chris, thanks for sharing your solution. This error might have occurred because Pandas 1.2.0 is a very recent release, and Heroku might not work well with that yet.

hi Orlanino, I did cover dash authorization. Here it is: kzfaq.info/get/bejne/g96Bp8p9u6vVkoU.html

you're welcome @Muntakimur. When you're ready and have a multipage app, you can watch the deployment of multipage app to heroku

not that I know of. But if you're successful, please let us know how you did it.

You're right. That's a good idea Ahmadnadeem, but you should be able to change the default page so it is the homepage

Hi Alison, maybe you can do that with Dash tabs or dash multipage app. I have a video on that

Hi Brandon, unfortunately my time is really limited. But I do offer consultation to my supporters on KZfaq or www.patreon.com/charmingdata

HI @Nicole I'm sorry but I've never seen this error

Never mind, I figured it out. Thanks so much for this video/channel, it is incredibly helpful!

there seems to be a bug in PyCharm, I found 2 solutions for this: 1. Open atom editor and edit the Procfile (or) 2. Run this in command line: echo "web: gunicorn index:server" > Procfile

@@vinrayudu I wasn't aware of that, @Vin. Thanks for sharing with others.

Hi @Negar, there's a need way to develop multi page app. It's still a beta version but it won't change that nick from here. github.com/plotly/dash-labs/blob/main/docs/08-MultiPageDashApp.md

@@CharmingData Thank you so much for your fast and comprehensive reply. I really appreciate it.

Philip, does your app work when not on heroku, on your computer?

Hi Stefan, you can use as many css files as you'd like. Just put them inside the assets folder, like I do in some of my videos

Hi @Siddharth, yes, you would. Unless you want to clean the data in the code, but that means that every time a user runs the app, the data gets cleaned, which might be a waste of resources.

@@CharmingData Thanks Adam, I applied your suggestion and I now have much cleaner looking code. However, I still have three more questions 1. Does Heroku CLI and the folder with the virtualenv need to be in the same directory that is C, D, or E? My Heroku CLI is created in the C drive whereas the app folder with virtualenv is in E drive. 2. I am getting an error called worker failed to boot, what does it mean ? 3.Can we use Dash Bootstrap Components within the python files for this example?

Hi Anuj what does your folder structure look like?

And when do you get that error?

What do you mean @Rohit?

Hi @Sai, I offer a very low price for consultation. Feel free to sign up for an All-purpose patreon and we can connect via video to try and figure out the problem. I'd be more than happy to help. www.patreon.com/charmingdata

Hi Alex, can you please share the exact spelling and space used when adding the line: heroku git:remote -a... Do you have a space between "git:" and "remote"?

@@CharmingData Hi Adam..now it's running fine i just closed the app and restarted the computer ... And when i tried the step ..it just worked fine thanks, great tutorial it is helping me alot.

@@_direto_e_reto nice

Hi Ifran. You can deploy to the web, but add a password so only your colleagues can access it.

@@CharmingData, inputs and ouput of my app are company specific confidential info. So It's illegal to upload it on internet. Is there another way ?

Right. That's normal. Changes to the CSS should appear if you refresh page, but changes to the code would appear only after saving and re-running
