Consider the following piece of code :
<script type="text/javascript" src="/<Computed Value>/samples/home.js"></script>
In the above example, how does 'Computed Value' get populated. I mean what is the general way of doing it in extjs?.
Thanks in advance.
Take a look at the Ext.String.format function: http://docs-origin.sencha.com/extjs/4.1.3/#!/api/Ext.String-method-format. It should do what you need:
var cls = 'my-class',
text = 'Some text';
var s = Ext.String.format('<div class="{0}">{1}</div>', cls, text);
// s now contains the string: '<div class="my-class">Some text</div>'

hello in vuejs I want to separate the amount of money with a comma and a period, how can I do it with filter?
I want the currency to be like this.
<p>1.000<span>,00</span></p>
I want the part separated by comma to be gray like in the image
Vue.filter('toTL', function (value) {
return new Intl.NumberFormat('tr-TR', { currency: 'TRY', minimumFractionDigits: 2}).format(value);
});
An easy solution would be to let the filter output the HTML:
<p class="amount" v-html="$options.filters.toTL(attributes.gross_total)" />
The filter can be written like so:
Vue.filter('toTL', function (value) {
let formatted = new Intl.NumberFormat('tr-TR', { currency: 'TRY', minimumFractionDigits: 2}).format(value);
let arr = formatted.split(',');
return arr[0] + '<span>,' + arr[1] + '</span>';
});

VueJS2 v-html with filter
Let's say I extract some classes from some HTML:
p_standards = soup.find_all("p",attrs={'class':re.compile(r"Standard|P3")})
for p_standard in p_standards:
print(p_standard)
And the output looks like this:
<p class="P3">a</p>
<p class="Standard">b</p>
<p class="P3">c</p>
<p class="Standard">d</p>
And let's say I only wanted to print the text inside the P3 classes so that the output looks like:
a
c
I thought this code below would work, but it didn't. How can I compare the class name of the container tag to some value?
p_standards = soup.find_all("p",attrs={'class':re.compile(r"Standard|P3")})
for p_standard in p_standards:
if p_standard.get("class") == "P3":
print(p_standard.get_text())
I'm aware that in my first line, I could have simply done r"P3" instead of r"Standard|P3", but this is only a small fraction of the actual code (not the full story), and I need to leave that first line as it is.
Note: doing something like .find("p", class_ = "P3") only works for descendants, not for the container tag.
OK, so after playing around with the code, it turns out that
p_standard.get("class")[0] == "P3"
works. (I was missing the [0])
So this code works:
p_standards = soup.find_all("p",attrs={'class':re.compile(r"Standard|P3")})
for p_standard in p_standards:
if p_standard.get("class")[0] == "P3":
print(p_standard.get_text())
I think the following is more efficient. Use select and CSS Or syntax to gather list based on either class.
from bs4 import BeautifulSoup as bs
html = '''
<html>
<head></head>
<body>
<p class="P3">a</p>
<p class="Standard">b</p>
<p class="P3">c</p>
<p class="Standard">d</p>
</body>
</html>
'''
soup = bs(html, 'lxml')
p_standards = soup.select('.Standard,.P3')
for p_standard in p_standards:
if 'P3' in p_standard['class']:
print(item.text)
I am new to laravel and I experience some trouble. I try to obtain data stored in two different tables and display them:
News.php (model)
public static function Data($category) {
$perPage = config('var.news.perPage');
if ($category) {
$news = News::orderBy('id', 'desc')->where('category', $category)->SimplePaginate($perPage);
} else {
$news = News::orderBy('id', 'desc')->SimplePaginate($perPage);
}
return $news;
}
This is how I grab all data from News table which struct is:
id, title, body, created_at updated_at, created_by, updated_by, category
The category column contains values separated by comma, e.g. 1,2,3,4
Now, I have another table, News_Cat which has id, name columns.
In another method I try to grab the filters names against values stored in category column of News table
public static function getFilterNames($id) {
$filters = DB::table('News_Cat')
->select('News_Cat.name as name')
->leftJoin('News', DB::raw('CAST(News_Cat.id as nvarchar)'), DB::raw('ANY(SELECT(News.category))'))
->where('News.id', $id)
->get();
return $filters;
}
However, it completely does not work. What I try to achieve is to display filter name in view.blade as 'name' value for specified filter from News_Cat
#if($news->count())
#foreach($news as $article)
<a href="{{ route('news.show', $article->id) }}" class="item angled-bg" data-filters="{{ $filters }}">
<div class="row">
So as result I would get e.g. data-filters="news, update, hot, latest"> instead data-filters="1,2,3,4">
Thank you
You should use eloquent!
In your News Model
public function getFiltersAttribute(){
$categories = explode(',', $this->category);
return implode(', ', NewsCat::find($categories)->pluck('name')->toArray());
}
then in your view :
{{ $article->filters }}
will output news, update, hot, latest
BUT
You should use a pivot table between your categories and your news, it would be much easier.
This method can't allow you to eager load the relationship and make a request for each news
If you can't change your database structure, I can propose you this:
In the boot method of your AppServiceProvider:
Config::set('tags', NewsCat::all());
THEN
public function getFiltersAttribute(){
$categories = explode(',' $this->category);
return implode(', ', config('tags')->whereIn('id', $categories)->pluck('name')->toArray());
}
MANY TO MANY METHOD
I am using laravel naming convention for the table :
news, categories_news (the pivot), and categories
You will have 2 models : New and Category
In your New Model
public function categories(){
return $this->belongsToMany(Category::class)
}
in your Category Model :
public function news(){
return $this->belongsToMany(New::class);
}
if you are not using laravel naming conventions, you will have to customize these raltionship like this : https://laravel.com/docs/5.5/eloquent-relationships#many-to-many
i want to get some database tables from my typo3 extensions.
The Extension is based on extbase.
The query always returns nothing but the data exists
I've tried this:
$query = $this->createQuery();
$query->statement('SELECT * FROM `my_table`
WHERE field = ? ORDER BY date DESC LIMIT 1',
array($condition));
$results = $query->execute();
and this:
$query = $this->createQuery();
$query->matching($query->equals('field', $condition));
$query->setOrderings(array('date' => Tx_Extbase_Persistence_QueryInterface::ORDER_DESCENDING));
$query->setLimit(1);
$results = $query->execute();
both returns null as result.
Is it possible to get the sql that the class creates to look where the bug is?
I've looked in some extbase persistent classes but didn't find a clue
EDIT:
For those who are interested.. i found a "solution".
If you create the query with the statement() method, you can print the query with this function
echo $query->getStatement()->getStatement();
It doesn't replace the placeholder.
But you can get the Variables with this method
var_dump($query->getStatement()->getBoundVariables());
Thats the best Solution that i found, without editing the extbase extenstions
In TYPO3 6.2 you can use Extbase DebuggerUtility to debug the query.
Add this code before $query->execute():
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbQueryParser');
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->parseQuery($query));
For TYPO3 8.7+ use this code instead:
$queryParser = \TYPO3\CMS\Core\Utility\GeneralUtilityGeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
$doctrineQueryBuilder = $queryParser->convertQueryToDoctrineQueryBuilder($query);
$doctrineQueryBuilderSQL = $doctrineQueryBuilder->getSQL();
$doctrineQueryBuilderParameters = $doctrineQueryBuilder->getParameters();
Check this snippet, although it's not very comfortable in use it helps a lot:
in general you need this code at the end of the buildQuery(array $sql) method (*) - right before return $statement;
if (in_array("your_table_name", $sql['tables'])) {
var_dump($statement);
print_r($statement);
}
(*) Class file:
TYPO3 ver.: 4.x: typo3/sysext/extbase/Classes/Persistence/Storage/Typo3DbBackend.php
TYPO3 ver.: 6.x: typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php
In 6.2.x ...
You can try within \TYPO3\CMS\Core\Database\DatabaseConnection::exec_SELECTquery method, just add the condition after fetching the $query, like (trim is important!):
public function exec_SELECTquery($select_fields, $from_table, $where_clause, $groupBy = '', $orderBy = '', $limit = '') {
$query = $this->SELECTquery($select_fields, $from_table, $where_clause, $groupBy, $orderBy, $limit);
if (trim($from_table) == 'fe_users') {
DebuggerUtility::var_dump($query);
}
// rest of method
An easy way without changing any Typo3 core code and not mentioned in any forum so far is using the php "serialize()" method:
$result = $query->execute();
echo (serialize($result));
In the result object you find the SQL query ("statement;" ...)
Improvement to biesiors answer:
As Extbase replaces some placeholders after calling buildQuery(), you might prefer to place the debug output into getObjectDataByQuery(), just after $this->replacePlaceholders($sql, $parameters, $tableName);
if (strpos($sql, "your_table_name.")) {
debug($sql, 'my debug output');
};
Also, better use debug() instead of var_dump().
[File: typo3\sysext\extbase\Classes\Persistence\Generic\Storage\Typo3DbBackend.php. Line 339 in version 6.1]:
$query = $this->createQuery();
$query->getQuerySettings()->setReturnRawQueryResult(TRUE);
$getHotelInfo = 'SELECT * FROM `my_table` WHERE field = ? ORDER BY date DESC LIMIT 1';
return $query->statement($getHotelInfo)->execute();
For executing query you have to write 'setReturnQueryResult' on your repository
I just extended the above snippet, with a $_GET condition.
for debugging, just append "?dbg_table=tx_some_of_my_tables" to your address, and you're ready to go ;-)
if (in_array($_GET['dbg_table'], $sql['tables'])) {
echo('<div style="background: #ebebeb; border: 1px solid #999; margin-bottom: 20px; padding: 10px;"><pre style="white-space: normal">'.$statement.'</pre></div>');
}
A cleaner way to debug your statements when using TYPO3 6.1 is to use the query parser of Typo3DbBackend.
$parser = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Persistence\\Generic\\Storage\\Typo3DbBackend');
$params = array();
$queryParts = $parser->parseQuery($query, $params);
\TYPO3\CMS\Core\Utility\GeneralUtility::devLog('query', 'my_extension', 1, array('query' => $queryParts, 'params' => $params));
The parser returns an array containing the different parts of the generated SQL statement.
With TYPO3 6.2 the parseQuery method was moved to Typo3DbQueryParser and lost its second parameter.
i suggest set this in typo3conf/LocalConfiguration.php file under 'SYS' array
'SYS' => array(
......
'displayErrors' => 1,
'sqlDebug' => 1
.......
)
and then write wrong field name in query intentionally and then execute code.
this will show last query execute with error.
Using nodejs, mongoskin.. I'd like to return the updated doc so Im using findAndModify, however the query {_id: "someid"} doesn't work. I think I need to use {id: ObjectID{'someid'} as the query. How do I get the ObjectId type into JS?
try this:
ObjectID = require('mongoskin').ObjectID
{_id: new ObjectID("someid")}
Here is a solution
var mongo = require("mongoskin");
var conn = mongo.db(YOUR_DETAILS);
var BSON = mongo.BSONPure;
this enables you to convert your id int, string or whatever using:
conn.collection(YOUR_COLLECTION).find({_id:new BSON.ObjectID(YOUR_ID)})
Hope that helps!
You can do something like:
yourCollection = db.collections('yourCollection');
Then
{ _id: yourCollection.id("someId") }
