I'm still pretty new to Grails and I'm developing an online survey. I decided to use web flow and I have been running into many issues. I'm trying to pass the survey id from the gsp page to the flow controller. This works perfectly fine on any other controller action but whenever I do it to the action for the start state of the flow I always get the same error. I've followed a tutorial in a text book that does this the EXACT same way and I'm running out of ideas.
here is the link from the gsp page:
<g:link controller="surveyPage" action="beginTest" id="${survey.id}">
${survey.surveyName}
</g:link>
and here is the flow with the start state
def beginTestFlow = {
showSurvey{
def survey = Survey.get(params.id)
on("cancel").to "cancelSurvey"
on("continueSurvey").to "nextQuestion"
}
cancelSurvey { redirect(controller:"surveyPage") }
}
it always throws the exception:
argument type mismatch on the line with
def survey = Survey.get(params.id)
I've also tried:
flow.survey = Survey.get(params.id)
or even:
flow.survey = Survey.get(session.survey.id)
always the same error. Also, I made sure class Survey implements Serializable. I've copied and pasted the same code into a different action with the same controller and it works flawlessly. Any ideas to what is different with the web flow?
You can't put code like that directly inside a state definition, you need to use an action state or an onEntry block
def beginTestFlow = {
showSurvey{
onEntry {
flow.survey = Survey.get(params.id)
}
on("cancel").to "cancelSurvey"
on("continueSurvey").to "nextQuestion"
}
cancelSurvey { redirect(controller:"surveyPage") }
}
The onEntry block will fire every time the showSurvey state is entered. If instead you want some logic to be run just once at the start of the whole flow (for example if some later transition might re-enter the initial state), you can use a flow-level onStart block instead:
def beginTestFlow = {
onStart {
flow.survey = Survey.get(params.id)
}
showSurvey{
on("cancel").to "cancelSurvey"

I have this code in my controller class:
public function actionRevoke($id) {
$model = Token::findById($id);
$model->revoked_at = new Expression('NOW()');
if ($model->save()) {
Yii::$app->getSession()->setFlash('success', 'Revoked token');
} else {
Yii::$app->getSession()->setFlash('danger', 'Failed to revoke token');
}
return $this->render('revoke',['model' => $this]);
}
Now, running CodeCeption with code coverage, it tells me, the part with setFlash('danger',...) is not covered by tests.
How can I intentionally fail the $model->save() to trigger the setFlash('danger,...) instruction?
I would really like it, if I do not need to add extra code to my Controller exclusively for testing. So in particular, I don't want something like if ($model->save() && !defined('TEST_FAIL_SAVE')) { if it can be avoided.
The solution was (as suggested by #scaisEdge) to use validation rules. I added a rule, which enforces the length of $model->token to exactly 36. My application generates only tokens exactly 36 chars long. In my test, I use update the row in the database to show abcd as token, which is clearly less than 36 chars.
As this change is made on database level, it bypasses the validation of Yii and is committed to the database.
During the test, it changes the value of $model->revoked_at and attempts to save it, but fails the validation because $model->token is too short.
Here is the relevant part in the test function, the code of the controller was not changed:
public function revokeToken(FunctionalTester $I){
// login and navigation to relevant page
Yii::$app->db->createCommand()->update('tokens',['token' => 'abcd'],['id' => 201 ])->execute();
$I->click('a.btn.btn-danger'); /* click the 'revoke' button, this triggers actionRevoke($id) */
$I->seeFlash('Failed to revoke token'); /* expect a flash message */
}
I just recently upgraded Umbraco from 4.7.2 to 7.1.9 and now in the process of slowly converting all legacy macroscripts to partial view macros. I have come across a few issues when using DescendantsOrSelf to iterate through nodes.
I have a macro that generates the side menu for my site (intranet). With version 4 the macro worked as expected on the whole site displaying the appropriate menu on the homepage and different side menu's on the child pages.
After the upgrade the below condition:
var model = GetParentSideMenu(CurrentPage);
#if (CurrentPage.AncestorsOrSelf("umbSomePageType").Where("Visible").First().HasValue("PageName") && CurrentPage.AncestorsOrSelf("umbSomePageType").Where("Visible").First().Id != model.Id)
{ ... }
#functions
{
public dynamic GetParentSideMenu(dynamic model)
{
if (model.Level > 1)
{
do
{
if (model.umbSideMenuLinks.Count() > 0)
{
return model;
}
if (model.Level > 1) {
model = model.Up();
} else { break; }
} while (model.Up() != null);
return model;
}
else return model;
}
}
Generates the following error when rendered on the homepage:
System.InvalidOperationException {"Sequence contains no elements"}
Inner Exception is null
The understanding here is that the page being rendered is not "umbSomePageType" so this condition should be false and move on but instead it throws the above exception.
The macro works fine when rendered on a "umbSomePageType" page but as the user is allowed to have further sub pages of a another type under "umbSomePageType" I have to manually check the "DocumentTypeAlias" and make sure the other if statements checking for that type of sub page are not executed because I get the same error as above.
Another issue I am facing is this doesn't return an iterable collection when it used to before in v4:
#if (model.DescendantsOrSelf("umbSideMenuLinks").Where("Visible").Count() > 0)
{
foreach (var item in model.DescendantsOrSelf("umbSideMenuLinks").Where("Visible").First().Children)
{ ... }
.... }
The if condition returns true but the foreach is unable to get any elements to iterate through.
Any help here will be greatly appreciated.
Thank You.
I was able to find a solution to the first problem I specified above. The error was occurring in the "if" condition due to the "CurrentPage" being a dynamic object, "FirstOrDefault()" needs to be used instead of "First()".
The second issue still stands and to further detail that issue if you have the following directory structure:
Root Folder/Homepage
- Second Level Folder
-- SideMenuLinks (umbSideMenuLinks)
-- SomePage...
- SideMenuLinks (umbSideMenuLinks)
In the above case if I am on the "HomePage" and I want to render the "SideMenuLinks" pertaining to the homepage and I use "DecedantOrSelf" it will go from the root folder to the second level folder and to the "SideMenuLinks" instead of first checking it "Self" which is the behaviour I desire. This is something that worked in Umbraco v4 but in v7 it drills into the sub directories first.
Maybe if I reorder/sort the SideMenuLinks so they appear before the "Second Level Folder" ?
Haven't tried that yet.
UPDATE: So I just tried the sorting and if I sort the tree this way:
Root Folder/Homepage
- SideMenuLinks (umbSideMenuLinks)
- Second Level Folder
-- SideMenuLinks (umbSideMenuLinks)
-- SomePage...
It starts to work. In the future we will have to create the page structure this to make sure that the correct SideMenuLinks are hit.
So I am trying to create a script whereby depending on the document type of the page a certain pre-defined title tag format will appear, if there is nothing already written in an overwriting custom title input. I have inserted the macro within the title tag on my master template but keep on getting an Error loading Razor Script message .
Html
<title>
<umbraco:Macro Alias="NewPageTitle" runat="server"></umbraco:Macro>
</title>
Script -
#inherits umbraco.MacroEngines.DynamicNodeContext
#using umbraco.MacroEngines
#{
if(String.IsNullOrEmpty(#Model.tabName.ToString()) == false )
{
#Model.tabName
}
else if(#Model.DescendantsOrSelf("Country"))
{
<text>
Holidays in #Model.Name
</text>
}
else
{
#Model.Name;
}
}
Any help would be greatly appreciated.
Try this code out. The problem with your original code is that you were using "#Model.DescendantsOrSelf("Country")" as a boolean, and it is a list. I also removed your comparison for if(String.IsNullOrEmpty(#Model.tabName.ToString())).
Also, if you add ?umbDebugShowTrace=true to the end of your URL, you can get some valuable debugging information. There is a Chrome Extension called "Umbraco Debug" that I use to quickly access that query string and information. You may find it useful.
#inherits umbraco.MacroEngines.DynamicNodeContext
#using umbraco.MacroEngines
#{
if(String.IsNullOrEmpty(#Model.tabName.ToString()))
{
#Model.tabName
}
else if(#Model.DescendantsOrSelf("Country").Count() > 0)
{
<text>
Holidays in #Model.Name
</text>
}
else
{
#Model.Name;
}
}
its very simple just add following code into your title tag
#Umbraco.Field("pageName")
will display pageName,you may also add custom properties from document type.
e.g. you have added new property like "metaKeywords" with value "html,javascript,xml",fetch that values as following way...
#Umbraco.Field("metaKeywords")
even you don't need to add custom properties in your model
When I create plane java Swing components like dialog boxes etc, it is very easy to make a unit test to display the Dialog. Basically, I can just create an instance of the dialog and call setIsVisible(true). I'm having a really tough time figuring out how to do this with a griffon View. I've been trying to do this with integration tests but I can't seem to get it.
I've tried a few things to show the view and nothing seems to work. The only way I seem to be able to get an instance of the view is:
AirplaneView view = helper.newInstance(app, griffonpractice.AirplaneView.class, "Airplane")
After this I thought I may be able to do a view.setIsVisible(true) or view.frame.setIsVisible(true) but no luck. I'm guessing I am thinking about this the wrong way, there has to be a fairly simple way to do this. Any help is appreciated. My view looks like the following, note that there are no bindings so I shouldn't need to mock anything.
package griffonpractice
import javax.swing.JFrame
JFrame frame = application(title: 'GriffonPractice',
size: [320,480],
pack: true,
location: [50,50],
locationByPlatform:true){
borderLayout()
{
hbox(constraints: BL.NORTH)
{
label(text: "shane")
label(text: "Jack");
}
}
}
Have you tried using FEST? http://easytesting.org
The book Griffon in Action has a detailed example on testing a Griffon application using FEST, the source code is available at http://code.google.com/p/griffoninaction/source/browse/trunk/chap09/dictionary
Here's a short example of 3 tests for a simple application
package dictionary
import org.fest.swing.fixture.*
import griffon.fest.FestSwingTestCase
class DictionaryTests extends FestSwingTestCase {
void testInitialState() {
window.button('search').requireDisabled()
}
void testWordIsFound() {
window.with {
textBox('word').enterText('griffon')
button('search').click()
textBox('result')
.requireText('griffon: Grails inspired desktop application development platform.')
}
}
void testWordIsNotFound() {
window.with {
textBox('word').enterText('spock')
button('search').click()
textBox('result')
.requireText("spock: Word doesn't exist in dictionary")
}
}
protected void onTearDown() {
app.models.dictionary.with {
word = ""
result = ""
}
}
}
I have a simple function that I want to call in the code behind file name Move
and I was trying to see how this can be done and Im not using asp image button because not trying to use asp server side controls since they tend not to work well with ASP.net MVC..the way it is set up now it will look for a javascript function named Move but I want it to call a function named move in code behind of the same view
<img alt='move' id="Move" src="/Content/img/hPrevious.png" onclick="Move()"/>
protected void Move(){
}
//based on Search criteria update a new table
protected void Search(object sender EventArgs e)
{
for (int i = 0; i < data.Count; i++){
HtmlTableRow row = new HtmlTableRow();
HtmlTableCell CheckCell = new HtmlTableCell();
HtmlTableCell firstCell = new HtmlTableCell();
HtmlTableCell SecondCell = new HtmlTableCell();
CheckBox Check = new CheckBox();
Check.ID = data[i].ID;
CheckCell.Controls.Add(Check);
lbl1.Text = data[i].Date;
lbl2.Text = data[i].Name;
row.Cells.Add(CheckCell);
row.Cells.Add(firstCell);
row.Cells.Add(SecondCell);
Table.Rows.Add(row);
}
}
Scott Guthrie has a very good example on how to do this using routing rules.
This would give you the ability to have the user navigate to a URL in the format /Search/[Query]/[PageNumber] like http://site/Search/Hippopotamus/3 and it would show page 3 of the search results for hippopotamus.
Then in your view just make the next button point to "http://site/Search/Hippopotamus/4", no javascript required.
Of course if you wanted to use javascript you could do something like this:
function Move() {
var href = 'http://blah/Search/Hippopotamus/2';
var slashPos = href.lastIndexOf('/');
var page = parseInt(href.substring(slashPos + 1, href.length));
href = href.substring(0, slashPos + 1);
window.location = href + (++page);
}
But that is much more convoluted than just incrementing the page number parameter in the controller and setting the URL of the next button.
You cannot do postbacks or call anything in a view from JavaScript in an ASP.NET MVC application. Anything you want to call from JavaScript must be an action on a controller. It's hard to say more without having more details about what you're trying to do, but if you want to call some method "Move" in your web application from JavaScript, then "Move" must be an action on a controller.
Based on comments, I'm going to update this answer with a more complete description of how you might implement what I understand as the problem described in the question. However, there's quite a bit of information missing from the question so I'm speculating here. Hopefully, the general idea will get through, even if some of the details do not match TStamper's exact code.
Let's start with a Controller action:
public ActionResult ShowMyPage();
{
return View();
}
Now I know that I want to re-display this page, and do so using an argument passed from a JavaScript function in the page. Since I'll be displaying the same page again, I'll just alter the action to take an argument. String arguments are nullable, so I can continue to do the initial display of the page as I always have, without having to worry about specifying some kind of default value for the argument. Here's the new version:
public ActionResult ShowMyPage(string searchQuery);
{
ViewData["SearchQuery"] = searchQuery;
return View();
}
Now I need to call this page again in JavaScript. So I use the same URL I used to display the page initially, but I append a query string parameter with the table name:
http://example.com/MyControllerName/ShowMyPage?searchQuery=tableName
Finally, in my aspx I can call a code behind function, passing the searchQuery from the view data. Once again, I have strong reservations about using code behind in an MVC application, but this will work.
How to call a code-behind function in aspx:
<% Search(ViewData["searchQuery"]); %>
I've changed the arguments. Since you're not handling an event (with a few exceptions, such as Page_Load, there aren't any in MVC), the Search function doesn't need the signature of an event handler. But I did add the "tablename" argument so that you can pass that from the aspx.
Once more, I'll express my reservations about doing this in code behind. It strikes me that you are trying to use standard ASP.NET techniques inside of the MVC framework, when MVC works differently. I'd strongly suggest going through the MVC tutorials to see examples of more standard ways of doing this sort of thing.
