I'm porting an existent L3 project into L4.
In my login view I've used {{ Form::checkbox('remember', 'remember', Input::had('remember')) }} to repopulate the status of remember me button.
However, in L4, Input::had is deprecated. So what's the substitution of Input::had()? Or there's another sexier way to repopulate status of a checkbox?
Use
{{ Form::checkbox('remember', 'remember', null !== Input::old('remember')) }}

I am struggling to include values into my alerting template
(Using Grafana 9.03 with classic condition alerting)
Query
Alert Evaluation
I tried to use {{ $values.B0 }} which works but only displaying the value. I want to use the Tag "Limit" for example "ImportStatNSC4903"
I did some more tries with:
{{ $values.B0.Limit }}
{{ $values.B0.labels }}
{{ $labels }}
Any ideas what I am doing wrong?
I am struggling to include values into my alerting template. I want a summery that tells me clearly why this alert was triggered
For example:
Limit ImportStatNSC4903 is outside the defined Boundaries
I am trying to debug one of my Helm charts and I noticed that the app.kubernetes.io/version label is created using the following code (in _helpers.tpl):
{{- if .Chart.AppVersion }}
app.kubernetes.io/version: {{ .Chart.AppVersion | quote }}
{{- end }}
But the actual variable is called appVersion. Similar inconsistencies exist with version and name. The use of them is using PascalCase, but the definition is using camelCase. I tried to google it, but can't find any info on it.
Are Helm variables really case insensitive? Or is there some kind of conversion going on behind the scenes.
The fields in the built-in objects are generally capitalized. That documentation also includes an example using {{ .Chart.Name }}-{{ .Chart.Version }}. Even though .Chart contains the contents of the chart.yaml file, its fields follow this convention.
Field access is case-sensitive and if you reference .Chart.appVersion you should get an error.
At an implementation level, the Go template . operator can either navigate a Go object tree or a Go map. The top-level object is a mix of maps and objects. .Values is an unstructured map; a release can include any values it wants in essentially any YAML layout. .Release turns out to be a map too, but with fixed known keys.
.Chart is a chart.Metadata object (not the parsed YAML directly but an object form of it). Its fields are visible to the template engine. Go's rule is that structure fields that begin with capital letters are visible, and that capitalization carries through back to the template engine.
I need display particular fields in form in Symfony 2.6. I use a class Form. I have the folowing fields: name, email, message, send, recet. I need display all of them except recet .I try like this:
{{form_start(form)}}
{{ form_errors(form) }}
{{form_row(form.name)}}
{{form_row(form.email)}}
{{form_row(form.message)}}
{{form_end(form)}}
But, it's displaying all fields in form, it is not what I want. Even if i leave only {{form_start(form)}} and {{form_end(form)}} - its display all fields. Can someone help me wit this problem?
remove form_end, just close form with HTML
</form>
but then you must handle CSRF token generation by adding:
{{ form_widget(form._token) }}
{{ form_widget(form._token) }}
or try setting field you do not want to show using:
{% do form.recet.setRendered %}
but probably best way is not to add this field in the first place, rather than hiding it, by form options or event listeners depending on some criterias
A better solution is to remove the field from the form type. If you only remove it from the view, it may be interpreted as a blank submission for that field and delete existing data.
If you only use the form in one place, then just remove the field from the type. If you use it in multiple places, then you can selectively remove the field in a FormEvents::POST_SET_DATA event listener.
Why i have double error when i want to customize my form ?
Template:
<div>
{{ form_errors(edit_form.wiek) }}
{{ form_widget(edit_form.wiek) }}
</div>
HTML:
You probably see the error on the field level, but also on the form level. It can look like you have two errors especially if there's only one field in your form.
Dig into the customizing error output of the form cookbook for more details.
Edit
The doc gives a much better explanation :)
You can also customize the error output for just one specific field type. For example, certain errors that are more global to your form (i.e. not specific to just one field) are rendered separately, usually at the top of your form.
How can I explicitly print CSRF field instead of using {{ form_rest(form) }}?
I need this because I'm going to hide/show some fields based on conditions, however {{ form_rest(form) }} is going to print all of the remaining fields (which is what I'd like to avoid).
It can be done this way:
{{ form_widget(form._token) }}
Also you might want to consider adding fields conditionally in your form type instead of making that kind of decisions in a template.
