I am trying to query the country column from one of my table and trying to group them so that one country name appears only once.
The controller code is
ViewBag.Countries = (from pT in _context.InfoProducts
group pT by new { pT.Country } into g
select new
{
Country = g.Key.Country
}).ToList();
In my view I am trying to show this list of countries in a dropdown like this
<div class=" form-group">
#Html.Label("Country")
<div class="col-md-12 ">
#Html.DropDownList("Country", new SelectList(ViewBag.Countries, "Country"), "Select Country", new { #class = "col-form-label col-md-12 label-align" })
</div>
</div>
The problem I am facing is though it is returning the expected names of the countries, the result is generating as a key, value pair something like
{Country = USA}
{Country = Canada}
The HTML generated copied from inspect element is given below
<select class="col-form-label col-md-12 label-align" id="Country" name="Country">
<option value="">Select Country</option>
<option>{ Country = USA}</option>
<option>{ Country = Canada}</option>
</select>
How can I get only the country name in the dropdown instead of the result I am currently getting.
Rather than using group by, it sounds like distinct would be a better fit:
_context.InfoProducts.Select(x => x.Country).Distinct().ToList();
This will give you back a list of strings to use, which won't give you the key-value pair problem you're currently having.
One more thing, when you use new SelectList(ViewBag.Countries, "Country") this overload of SelectList's constructor will try to set the value of Country as the selected item, but this doesn't exist in your list, so Select Country will always appear as selected. If you want that to select an actual country, then it would have to look something like:
new SelectList(ViewBag.Countries, "Canada")
where you would fetch Canada from the data for the current product.
Hello guys specially VueJS devs theres something weird happened. Ill explain it one by one

I use datatable and then i use this getDefaultPrice() to manipulate the price because the format of my price is like this ("65;75") to return the first value to PHP 65.00
then once i click the add to cart button please see image for codes the getDefaultPrice() also executed.
and I received an error "price.split is not a function" I tried to console.log the function and it really runs it without calling it in my add_to_cart();
<td>
<p>{{getDefaultPrice(product.price)}}</p>
</td>
<td>
<button
class="btn main_bg_color add_to_cart_btn" data-toggle="modal" data-target="#productModal"
#click="add_to_cart(product)"
>
<i class="fa fa-shopping-cart"></i> Add to cart
</button>
</td>
add_to_cart(product) {
this.modal_data = [];
this.modal_data.push(product)
this.modal_data[0].variation = this.modal_data[0].variation.split(';');
this.modal_data[0].price = this.modal_data[0].price.split(';');
this.modal_data[0].drinks_price = this.modal_data[0].drinks_price.split(';');
this.modal_data[0].drinks = this.modal_data[0].drinks.split(';');
},
getDefaultPrice(price) {
console.log("test")
var price_arr = price.split(";");
var default_price = parseFloat(price_arr[0]);
return "PHP " + default_price.toFixed(2);
},
I am currently facing a dilemma within the project I am currently completing. I have a database where two tables are linked through foreign keys which are of data type int.
What I am trying to do is retrieve a value from tblProductColour and using the INNER JOIN function add the information to the other table which is tblProducts.
Here is the controller code,
public ActionResult Index()
{
var db = WebMatrix.Data.Database.Open("Database");
if (Session["AdministrationTeam"] != null)
{
View = "ViewAllProducts";
}
else
{
return RedirectToAction("Login", "Home");
}
return View(View, odb.tblproducts.SqlQuery("SELECT * FROM tblproducts t INNER JOIN tblProductColour ot ON t.ID = ot.ProductColour"));
}
The getters and setters that are stored within the model itself are as shown below,
public int? ProductColour {get;set;}
Here is the code I am using in my View to retrieve the information from the model,
#foreach (var item in Model) {
<div class="col-lg-3 col-md-6 col-sm-6 ">
<img src="#item.ProductImagePath" alt="Image Should Show Here" style="margin:auto auto; background-color:#fff;" width="100%" height="20%"/>
<p>Product Id: #Html.DisplayFor(modelItem => item.Id) </p>
<p> Product Name: #Html.DisplayFor(modelItem => item.ProductName)</p>
<p>Supplier: #Html.DisplayFor(modelItem => item.ProductSupplier) </p>
<p>Colour: #Html.DisplayFor(modelIteem => item.ProductColour) </p>
<p>Product Quantity: #Html.DisplayFor(modelItem => item.ProductQuantity)</p>
<p> Product Description: #Html.DisplayFor(modelItem => item.ProductDescription)</p>
</div>
When retrieving the information, I am faced with this error shown below,
Conversion failed when converting the varchar value 'Red' to data type int.
Here are the entities,
tblproducts
tblProductColour
If anyone has any solutions to how I can display the information it would be appreciated.
You're joining the wrong items
"SELECT * FROM tblproducts t INNER JOIN tblProductColour ot ON t.ID = ot.ProductColour"
should be
"SELECT * FROM tblproducts t INNER JOIN tblProductColour ot ON t.ProductColour = ot.ID"
You then need to change
#Html.DisplayFor(modelIteem => item.ProductColour)
in your view to (assuming the correct reference name for the table is tblProductColours) to
#Html.DisplayFor(modelIteem => item.tblProductColours.ProductColour)
- or
#Html.DisplayFor(modelIteem => item.ProductColours.ProductColour) -
may also work - just depends on how it is referenced, hopefully autocomplete will help you out.
I just moved to the laravel framework and am starting to migrate some legacy sites and I have hit a problem with SQL or blade - dunno which.
I have to display a load of rows 'sports classes' which are grouped by year and then month. each needs to show attendance etc.
I am unsure which way to proceed.
I am able to display all rows and sort by date - easy squeezy
I am able to groupBy year AND month - fiddly but sorted it.
These are all displayed in an accordian.
Click the month - the individual rows drop down - you get the idea
I can get a number of rows per month/year
What I am unable to figure out is how to actually display the rows.
The groupBy is this:
$LinkClasses = DB::table('classes_lists')
->select('id, class, teacher, size')
->select(DB::raw('YEAR(date) AS year, MONTH(date) AS month, MONTHNAME(date) AS month_name, COUNT(*) post_count'))
->groupBy('year')
->groupBy('month')
->orderBy('year', 'desc')
->orderBy('month', 'desc')
->orderBy('id', 'desc')
If the code you provided is within your controller, then you can append ->get() after your last ->orderBy(). This will return a Collection. You can then do whatever you want with the Collection (http://laravel.com/api/master/Illuminate/Support/Collection.html), including conversion to an array using ->toArray(), but I think it would be best to utilize the Eloquent ORM if possible.
Anyway, once you have it in the format you want, just pass it to the view like so:
return view('your.view', compact('LinkClasses'));
Then, inside the your.view blade template, you can access this by using the following:
#foreach ($LinkClasses as $currentRow)
<tr>
<td>{{ $currentRow['id'] }}</td>
<td>{{ $currentRow['class'] }}</td>
<td> ... </td>
</tr>
#endforeach
Best guess I can offer without seeing the blade template to get a better idea of what you're doing. Hope that helps!
UPDATE BASED ON OP FEEDBACK:
Since you are only receiving a single record, it seems as though the issue lies in your query. I suggest you simplify your query to fetch all records and then do your sorting within an array. Something like this in your controller:
$allClasses = DB::table('classes_lists')->all();
foreach ($allClasses as $currentClass) {
$yearMonth = date('Y-m', $currentClass['date']);
$classesByYearMonth[$yearMonth][] = $currentClass;
}
ksort($classesByYearMonth);
/* now you have an array of all classes sorted by year-month like this:
// $classesByYearMonth[2014-01] = array(
// [0] => array(1, 'class name', 'teacher name', 23),
// [1] => array(2, 'another class', 'different teacher', 25),
// ...
// );
//
// $classesByYearMonth[2014-02] = ...
*/
return view('your.view', compact('classesByYearMonth'));
Then, inside your blade template:
#foreach ($classesByYearMonth as $yearMonth => $classListArray)
Found {{ sizeof($classListArray) }} classes for {{ $yearMonth }}
#foreach ($classListArray as $currentClass)
<div>
<div>ID: {{ $currentClass['id'] }}</div>
<div>Class: {{ $currentClass['class'] }}</div>
<div>Teacher: {{ $currentClass['teacher'] }}</div>
<div>Size: {{ $currentClass['size'] }}</div>
</div>
#endforeach
#endforeach
I will leave it to you to fix the formatting to make your accordion work. But hopefully that will get you on the right path.
DNoe - thank you so much.
Your reply put me on exactly the right track.
I had to mod some bits due to laravel ambiguities and add the strtotime but the logic was all there.
foreach ($allClasses as $currentClass) {
$ym = $currentClass['date'];
$yearMonth = date("Y-m",strtotime($ym));
$classesByYearMonth[$yearMonth][] = $currentClass;
}
krsort($classesByYearMonth);
return View::make('classes.index', compact('classesByYearMonth'));
The css is simple from here.
I owe you some beers. And thanks for helping me take my head from my butt!
Send me a pm and i would be very very happy to forward beer donation :o
Great work and thank you again. :)
Also, part of the problem was that the results were throwing an stdObject rather than an array.
Being able to compare your code with my own has enabled me to create a dbquery with multiple joins from which meaningfull data is selected and then converted to an array.
$classes = DB::table('table2')
->join('table1', 'table2.id', '=', 'table1.id2' )
->join('table3', 'table1.id3', '=', 'table3.id' )
->orderBy('classes_lists.date','DESC')
->get(array('table1.id', 'teacher', 'date', 'size', 'students', 'fname', 'classname', 'table1.notes'));
$cfr = count($classes);
foreach($classes as $object)
{
$arrays[] = (array) $object;
}
foreach ($arrays as $currentClass){
$ym = $currentClass['date'];
$yearMonth = date("Y-m",strtotime($ym));
$clazByYearMonth[$yearMonth][] = $currentClass;
}
krsort($clazByYearMonth);
This was the output into blade:
Not formatted :
#foreach ($clazByYearMonth as $yearMonth => $classListArray)
Found {{ sizeof($classListArray) }} classes for {{ $yearMonth }}
#foreach ($classListArray as $currentClass)
<div>
date: {{ $currentClass['date'] }} | class: {{ $currentClass['classname'] }} | Size: {{ $currentClass['size'] }} Teacher: {{ $currentClass['fname'] }} |
</div>
#endforeach
#endforeach
I want to select the record from the list box using text. how can i use the filter function to select the particular record. I will be having many options but i want to select the value which i want by checking the text (e.g Spanish). I dont want to select value by index becoz if i do that i wont be able to verify test, moreover list gets updated. kindly help. below r my html code.
<ul class="addList">
<li ng-repeat="skill in availableSkills" ng-click="addSkillFunc(skill, $index)" class="ng-binding ng-scope">Mandarin</li>
<li ng-repeat="skill in availableSkills" ng-click="addSkillFunc(skill, $index)" class="ng-binding ng-scope">English</li>
<li ng-repeat="skill in availableSkills" ng-click="addSkillFunc(skill, $index)" class="ng-binding ng-scope">Spanish</li>
</ul>
Yea i can select the record by index. but i want something like selectbyvisibleText which is available in Selenium.
Finally got the solution. created a function SelectRowByCellValue and used to call it where ever i want by
SelectRowByCellValue(AGP.SkillList, Data.SkillSelect);
SkillList = element.all(by.css('Ul.addList li'));
SkillSelect = Value that u want to select. (Spanish)
this.SelectRowByCellValue = function (Elem, Texts) {
Elem.filter(function (element) {
return element.getText().then(function (text) {
if (text == Texts) {
element.click();
return false;
}
});
}).then(function (filteredElements) {
});
};
