I am trying to deploy my shiny app on shinyapps.io. The app runs fine in my console but when I deploy my app I get errors for reactiveValues, such as:
object 'Logged' not found
OR
Error in reactiveValues(Logged = Logged, registed = registed, Foget = Foget, : object 'Logged' not found
My script is more than 1000 lines, so, I was not sure that it is a good way to upload the whole script, that's why I decided to put the first few lines from the server that are about the reactiveValues.
Appriciate!
server = (function(input, output,session) {
Logged = FALSE;
registed = FALSE;
Foget = FALSE;
Started = FALSE;
tested = FALSE;
Saved = FALSE;
USER <- reactiveValues(Logged = Logged,registed = registed, Foget=Foget, Started=Started,tested=tested,Saved=Saved)
...
...

Declare it as global variable using "<<-" I would suggest you to declare all variable as global variable.
The code should end by the following line:
shinyApp(ui = ui, server = server)

This was a complicating in logic execution i came across using {polished} and {brochure}.
When placing secure_ui/secure_server inside of a brochure::Page() in the same order of the example given by the {polished} dev team, there are changes to how a Shiny App is deploy on the {brochure} infrastructure. I was not sure where to relocate the polsiehd logic to.
Differences
no global.R file in a brochureApp()
multiple calls to different module_ui/server functions since each brochure::page() is its owns shiny session
single page shinyApp vs true multipage shinyApp
When needing to merge the two logics you must:
move polished_config() in globals.R --> golem::runApp() [initiate global setting for brochureApp()]
run_app <- function(
onStart = NULL,
options = list(),
enableBookmarking = NULL,
...
) {
# old 'globals.R' logic
polished_config(
app_name = "humblFinance",
api_key = "xxxx"
)
with_golem_options(
app = brochureApp(
# Putting the resources here
golem_add_external_resources(),
page1(),
),
golem_opts = list(...)
)
}
wrap each brochure::page() ui/server with polished::secure_ui/server()`
# an example login page
login <- function(id = "login", href = "/login") {
page(
href = href,
ui = secure_ui(
mod_login_ui(id = id),
sign_in_page_ui = sign_in_custom()
),
server = secure_server(
function(input, output, session) {
mod_login_server(id = id)
}
)
)
}
NOTE
sign_in_custom() is a function that returns a customized UI object from polished::sign_in_default() to create personal business webpages.
I would recommend wrapping polished::sign_in_default() in a custom global function since you will need to define this on ever brochure::page() that you want to have protected behind polished auth.
once you authenticate one page through polished, you will be able to access all other protected pages while you are still logged in. After loggign out and attempting to access any one of the protected pages will result in a custom login page
With the following piece of code I'm able to trigger a pure javascript alert by clicking on the question-mark of the fileInput:
fileInput('peptides',
span("Peptides file ",
id="peptidesSpan",
tags$a(
tags$i(class='fa fa-question-circle'),
href = "#",
onclick = "alert('Oops!'); return false;")
),
multiple=FALSE,
accept = c('text/csv','text/comma-separated-values',
)
)
I was wondering if I could trigger a shinyalert popup (https://github.com/daattali/shinyalert/) instead of a simple javascript alert directly form the UI without any observer in the server side.
Something like:
shinyalert("Oops!", "Something went wrong.", type = "error")
If there is not a workaround to do that, any other suggestion with an observer would be welcome as well.
I think using an observer is not at all inconvenient.
Instead of alert(), invoke Shiny.setInputValue(id, value);, and then on your server side you can observeEvent(input[id], { shinyalert() }).
Read this article for details: https://shiny.rstudio.com/articles/communicating-with-js.html
You only need to use one observe code block to achieve this.
An example
Define a customized function in your UI Javascript code and call it in your onclick.
You can put this function say in helper.js in the 'www' folder in your project folder, that will be www/helper.js. Include this file in your Shiny UI code by tags$head(tags$script(src = "helper.js"))
function showAlert(message, type = "info") {
Shiny.setInputValue(
'alertMessage',
{
message: message,
type: type
},
{ priority: 'event' }
);
}
Then on the Shiny server side define the observer once
observeEvent(input$alertMessage, {
alertData <- input$alertMessage
req(alertData)
shinyalert("title", alertData$message, type = alertData$type)
})
It's one of the few times that I answer my own post, but after searching a bit more on stack-overflow I found a workaround inspired by this post.
I downloaded the sweetAlert.js file of the Sweet Alert library directly from here
I create a www folder in the root of my Shiny application
I added the sweetAlert.js file in the www directory and in the dashboardBody() of the ui.R I added the following line:
tags$head(tags$script(src="sweetAlert.js"))
Now I'm able to call directly the Swal.fire function with any argument as I would normally do in any other framework which runs javascript.
I want to print multiple doc file on button click.I am using this code
ProcessStartInfo info = new ProcessStartInfo(txtFileName.Text.Trim());
info.Verb = "Print";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(info);
and the code is working fine in my application,but after publishing the application on the server ,i am unable to access the functionality.thanks in advance
I want to start a workflow programatically. So written a web script.
Execute Script :
function startWorkflow()
{
var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "activiti$alfGroupReview";
workflow.parameters["bpm:workflowDescription"] = "Please review ";
workflow.parameters["bpm:groupAssignee"] = people.getGroup( "GROUP_site_collaborators");;
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 7);
workflow.parameters["bpm:workflowDueDate"] = futureDate;
workflow.execute(document);
return ;
}
For the above script, I am getting error "document is not defined". I am referring https://forums.alfresco.com/en/viewtopic.php?f=34&t=42677 and http://livinginjava.blogspot.in/2008/10/starting-alfresco-workflow-using.html links.
So I update my script to :
function startWorkflow()
{
var nodeRef = "workspace://SpacesStore/25285e6c-2995-49fe-aa50-1270cefc806a";
var docNode = search.findNode(nodeRef);
var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "activiti$alfGroupReview";
workflow.parameters["bpm:workflowDescription"] = "Please review ";
workflow.parameters["bpm:groupAssignee"] = people.getGroup( "GROUP_aloha_collaborators");;
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 7);
workflow.parameters["bpm:workflowDueDate"] = futureDate;
workflow.execute(docNode);
return ;
}
Here, nodeRef : is ref of a document from document library.
Now new error is :
500 Description: An error inside the HTTP server which prevented it from fulfilling the request.
Message: 06270056 Wrapped Exception (with status template): 06270273 Failed to execute script 'classpath*:alfresco/templates/webscripts/org/justransform/startWF.get.js': null

thanks in advance.
Using Alfresco Workflow API.
Note: wfDocs holds the array of doc nodes:
// 2 days from now
var dueDate2d = new Date((new Date()).getTime() + 2*(24*60*60*1000));
// Start workflow
var wfdef = workflow.getDefinitionByName("activiti$alfGroupReview");
if (wfdef) {
var wfparams = new Array();
wfparams["bpm:workflowDescription"] = "Please review";
wfparams["bpm:groupAssignee"] = people.getGroup( "GROUP_site_collaborators");
wfparams['bpm:workflowDueDate'] = dueDate2d;
wfparams['bpm:workflowPriority'] = 1;
wfparams['wf:notifyMe'] = true;
var wfpackage = workflow.createPackage();
for each (var n in wfDocs)
wfpackage.addNode(n);
var wfpath = wfdef.startWorkflow(wfpackage, wfparams);
var tasks = wfpath.getTasks();
for each (task in tasks)
task.endTask(null);
}
This code runs fine if:
docNode is not null. You should add a check for this.
Your group exists. Probably worth adding a check for this.
The workflow exists with the ID specified. Use the workflow console to confirm this. For example, the ID your provided is not an
out-of-the-box workflow. If it is custom, maybe you haven't deployed
the workflow successfully or you have the ID incorrect.
Also, do not use a variable called "workflow". Alfresco already defines a root-scoped object called "workflow". Speaking of that, feel free to use the workflow JavaScript API to invoke your workflow instead of an action. Either should work, though.
I ran your code successfully using the JavaScript console and a workflow id of "activiti$activitiParallelGroupReview" (and after changing your workflow variable to workflowAct).
I'm using signalr in my asp.net web forms application, all seems to work good, except that I'm getting exception on the line
$.connection.hub.start();
However, if I click no on "Do you want to Debug" popup, signalr functionality works pretty well. The full error message is this
Unable to get value of the property 'transports': object is null or undefined
And here is complete js code
var docStatusUpdate = $.connection.docstatus;
docStatusUpdate.statusUpdate = function (msg, session) {
var sessionId = $('input#sessionValue').val();
if (sessionId == session) {
$("#statusUpdateMsgContainer").text(msg);
}
};
docStatusUpdate.endProcessing = function (session) {
var sessionId = $('input#sessionValue').val();
if (sessionId == session) {
$('input[id*=btnRefresh]').click();
}
};
$.connection.hub.start();
function assignValues() {}
I'm using Asp.net 4.0, signalr is installed via nuget.
Any ideas how can I solve this ?
I had a discussion on http://jabbr.net regarding to this issue, and it turned out, that none of the suggestions work. The main thing was to make sure that jQuery library isn't referenced more than once. Anyways, I just deleted browser data, and it started to work as expected.
