I would like to store the dynamic variables from Shiny app to .Rprofile and .Renviron, so as i can read the variables when the R was restarted next time.
Some guys suggested the usethis can edit the .Rprofile and .Renviron, but i want the use the shiny ui to input the variables, and store into .Rprofile and .Renviron.
Thanks for your help.
Best,

I am trying to get my first dashboard with python dash running.
The whole thing is very similar to this https://github.com/dkrizman/dash-manufacture-spc-dashboard.
At the beginning a Dataframe is read in from a csv. My problem seems to be quite easy to solve but somehow I am not succeeding:
I want to create a initial window that allows the user to select (from e.g. dropdown) the csv file (or accordingly the path) that is read in. All the .csv files look the same but just have different values.
When using the modal components I get problems with the install of bootstrap and I thought there must be an easier way?
Thanks for your help!
Best,

I had dashboard that works great locally. The problem when I want to deploy it is that all my data sources are in my C drive.
I am not sure how to refer to a local file. I have seen many code examples and all refer to a sever somewhere.
Is it possible to referrer to a local file ?
library(shinydashboard)
library(shiny)
require(htmltools)
indicators <- read.csv ("C:/Users/user1/Desktop/idicators.csv")
thanks
You can refer a local file easily by storing in R with a particular
dataframe name.
Then you can use that dataframe name in any of your
R script as a variable name and then it will work fine.
I was charged with making some modification to an old application, and I created a new page which was being passed a URL parameter page_name, which is a you guessed it a name of a page with .cfm appended. So, in my haste, I continued using it, and was building out my CFC and using the page_name as the identifier for a record. Then I realized that there is a possibility of that name being duplicated in the table, and changed that url parameter to use the page_id, which is unique. I modified my CFC to use the new key, and nothing worked. So I started going through my code and figured I made a typo, started commenting things out, and finally dumped out my CFC object and voila, none of the edits I made were actually being used. This was fairly obvious, since page_name was a string, and page_id was numeric.
So I started googling,The first thing I saw as adjust things in the CFAdmin. I don't have access to it, and restarting the server isn't an option since I'm using an RDS to live code. The next thing I tried was to add applicationStop(), onApplicationStart(), to my Application.cfc. Well the problem is that the Application.cfc, is actually an Application.cfm. So after fiddling with the <cfapplication ... > tag, and nothing being updated, I'm here asking for help.
So is there a quick fix for this? Should I go ahead and create an application.cfc? I hope I explained myself, and sorry for all the text.
Confirm that your cfc is bound to either the session or application scope.
If it is, then you can rename the application in application.cfm and it will reset the object.
If your cfc is NOT bound to session or application scope, you have a cacheing issue. You need to go the the CF admin -> Server Settings -> Cache tab and uncheck component cache and possibly some others.
For further recommendations, ColdFusion Components Inheriting Functions Of Others
Sounds like you have been painted into a corner. Last option IF you have access the the server it self and can get into the C:\ or whatever drive that ColdFusion have been installed on, you can just manually delete the generated Java Class files that the server is using that has the old code. When ColdFusion sees there is no Class file it will recompile the newly changed file and whoa black betty go bam-a-lam your changes will be in production.

we are planing to create a CMS with zf2 and doctrine orm .
actually we are concern about our cms templating
we want our system works with several templates and easily change between themes via admin
and creating a new templates should be easy for end-users developers
we want an advice or suggest for how to build templating system that :
there is a core module and there a lot sub modules with their own phtml
so where to store theme1 phtml and where to store theme2 phtmls ...
any suggest or advice please
thanks
I encourage you to take a look at Twig, its the best template engine I have seen so far :) It does take some time to learn Twig syntax, but its well worthy if you look at what you get :)
I cant yet write comments, so I wrote this as an answare.
Hope this helps. Trust me, the Twig is the way to go. Joust look at his documentation for more specific details how to use it!
EDIT:
The problem you are trying to solve has nothing to do with template engine. You can do that with any template engine. You can do it even with plain PHP if you want.
I built web application where users can register, get their own sub domain, and there they can build their webpage. Change theme, edit text, add pages. Simple CMS functionality.
The easiest way to do this is to have themes folder, where you would store themes, like this:
themes/
- themeBlue
- css/
- images/
- js/
- html or views/
- themeRose
...
Now this is where you would place all your themes, every theme has its own folder with images, css, js files...
And then you would have users, and every user would be able to choose and change theme.
That information would be stored in database. You need to store that user Jack is using themeBlue. You can do that as you want. You can event put this in users table like user_theme column.
Now when someone visits site, you first query database to see what theme is that user or creator of web using. And then you load all that files from current theme folder. And populate html files with data stored in database like in any other CMS.
This is the simplest implementation. You could for example, store css and html files in database :)
Hope this answers your question.
Good luck with that, I almost gone mad building my system :) I ended up with writing my own PHP MVC Framework joust to accomplish what I wanted.
if you activate another module in the application.config.php which has the same views and layouts (same folder structure and filenames) it's viewscripts and layouts will automatically be used when it's loaded after your core module.
so you could simply make your application.config.php dynamic to load the active template module which only contains the view folder. this would be a simple and effective solution without any other libraries.
additionally you can use an asset manager like assetic to also provide images, css etc. inside of your (template-)modules. (have a look at zf2-assetic-module, I wrote my own assetize-module based on assetic to fit my needs...)
Sina,
I do this in my Application->Module.php onBootstrap
$ss = $serviceManager->get('application_settings_service');
$settings = $ss->loadSettings();
$serviceManager->get('translator');
$templatePathResolver = $serviceManager->get('Zend\View\Resolver\TemplatePathStack');
$templatePathResolver->setPaths(array(__DIR__ . '/view/'.$settings['theme'])); // here is your skin name
$viewModel = $application->getMvcEvent()->getViewModel();
$viewModel->themeurl = 'theme/'.$settings['theme'].'/';
In this situation I have this structure in my view folder
view/
default/
application/
error/
layout/
zfcuser/
red/
application/
error/
layout/
zfcuser/
The $viewmodel above injects a variable into the layout for the themeurl in the public_html folder /theme/red/ with all assets for red
Access in layout.phtml -> themeurl;?> in a viewscript layout()->themeurl;?>
I am still working out my Dynamic Views. Right now I have a BaseController and all my ActionControllers extend it. It has a render() function that builds the required views but not sure its going to be scalable hoping to try some placeholder ideas.
application_settings_service is a Settings Service that gets settings for whatever domain was used to call the system and builds an array accessible via any service aware part of the site. Thats a whole different post and it may or may not rub MVC peeps the wrong way
I know your question is marked answered just thought I would share

Please see the folder structure image in the above url mentioned please advice which structure would be best suited for better code managibility. If the above image is not gettign please use this url http://www.freeimagehosting.net/image.php?387990357b.jpg
As far as automated deployment goes, It would appear to me that your second option would be better... that will allow you to "pick up" either site 1 or site 2 all at once and drop it anywhere you want.
I use virtualenv to manage multiple sites, which is basically an extension of the second option: each with their own code base and settings file and modules.
this looks good: http://www.mail-archive.com/django-users#googlegroups.com/msg75840.html
