I am working on a code project for Udacity and I get these 2 errors I dont get I have attached the pictures. One error is with parenthesis and when I remove the parenthesis I get an error on the code saying invalid syntax.

Your init method has single underscores. It needs to have double underscores before and after "init".
def __init__(self, movie_title, movie_storyline, poster_image, trailer_youtube):
Also, you're missing a comma when you create the Movie_300 object. It should look like this (with a comma after the wikimedia link):
Movie_300 = Movie("300",
"300 spartans vs an amry of persians",
"https://upload.wikimedia.org/wikipedia/en/5/5c/300poster.jpg",
"https://www.youtube.com/watch?v=wDiUG52ZyHQ")
As an aside, the convention to name variables in Python is to use all lowercase.

I want to display percent instead of an integer.
Now it simply shows the value as integer when hovering on the data point of the chart (the tooltip).
I think I need to set in the formatter formula like this:
let test = value / SUM(all_values)
return test.toFixed(0) + '%'
But, I could not find it in their documentation, the best I found is this one which always gives me 100%, per every data point:
tooltip: {
y: {
formatter: function(value, opts) {
let percent = opts.w.globals.seriesPercent[opts.seriesIndex][opts.dataPointIndex];
return percent.toFixed(0) + '%'
}
}
}
You're right that you'll need to use the tooltip formatter, but the array you're using to get the percentage values isn't correct.
If you log the values opts.w.globals.seriesPercent you'll find that it's all 100's:
[[100, 100, 100, ..., 100]]
(I suspect this might be because it's intended to be used with other chart types.)
You can still get the percentage though, it'll just need to be worked out.
Using your same method to format the tooltip, but getting the values from opts.series instead:
tooltip: {
y: {
formatter: function(value, opts) {
const sum = opts.series[0].reduce((a, b) => a + b, 0);
const percent = (value / sum) * 100;
return percent.toFixed(0) + '%'
},
},
}

I'm building a rating system for my website. It's currently working well but I would like to improve the esthetical aspect of the system. I would like to be able to take the rating from the database and display it as a 5-stars rating. Also, if it's not overly complicated, I would like to be able to click on stars to record the rating in the database, rather than writing a number.
I'm quite new to web development. In particular, I have no experience with javascript (I only did tutorials found on internet), which I think is required to implement the functionality I'm searching for, so please gives me a little example with your response in order to make me able to understand.
For rendering the rating as stars, I have no idea how to do it. For recording the rating as stars, I thought about two solutions :
1) Using django star-ratings but I don't think I have the capabilities required to understand how it works. I already made a post to ask for help and examples about this app but I received no help so I guess I should forget this.
2) Using a form with some appropriate widget to render an IntegerInput as a 5-stars rating.
For the second solution, I already have the code, I now need a widget to replace 'Stars' in the code below but I'm not sure how to do it. Can someone help me ?
models.py
class Avis(models.Model):
note = models.IntegerField()
forms.py
class AvisForm(forms.ModelForm):
class Meta:
model = Avis
fields = ['note']
widgets = {'note': forms.NumberInput(attrs={'class': 'Stars'})}
labels = {'note': 'Note /5'}
hmtl for recording
<form method="post" action="">
{% csrf_token %}
{% for field in form %}
<div class="fieldWrapper form-group">
{{ field.label_tag }}
{{ field }}
</div>
{% endfor %}
<input type="submit" class="btn btn-lg btn-outline-primary btn-block btn-login text-uppercase font-
weight-bold mb-2" value="Envoyer mon avis" />
</form>
hmtl for displaying
{{ avis.note }}
Thanks in advance !
EDIT (my code so far for the ratings storing) :
views.py
def avis(request, id): # view for displaying and storing the form
commande = get_object_or_404(Commande, id=id)
if request.method == "POST":
form = AvisForm(request.POST)
if form.is_valid():
avis = form.save(commit = False)
avis.commande = commande
avis.save()
commande.has_avis = True
commande.save()
if commande.plat.chef.nb_avis==0:
commande.plat.chef.rating = avis.note
else:
commande.plat.chef.rating = (commande.plat.chef.rating*commande.plat.chef.nb_avis + avis.note)/(commande.plat.chef.nb_avis + 1)
commande.plat.chef.nb_avis += 1
commande.plat.chef.save()
messages.success(request, 'Votre avis a été correctement envoyé !')
return redirect(mes_commandes)
else:
form = AvisForm()
return render(request, 'actualites/avis.html', locals())
def avis2(request, id): # view for recording the rating
avis = get_object_or_404(Avis, id=id)
rating = request.POST.get('rating')
avis.note = rating
avis.save()

For Rendering the rating, you need to calculate the value first. You need to determine the number of person who rated 5, 3, ... 1 stars. Lets say there are 100's 5 star rating, 70 * 4 star, 50 * 3 star, 30 * 2 and 20 * 1 star rating. So you can determine rating by:
sum of rating / total rating
So it will be (100 * 5 + 70 * 4 + 50 * 3 + 30 * 2 + 20 * 1) / 100 + 70 + 50 + 30 + 20
So the final rating will be: 3.74
To get the width percentage: (3.74 * 100) / 5 = 74.8
Here 5 refers to total number of stars, here I am assuming that rating will be based on the scale of 5.
For rendering you will need different HTML and CSS.

You need to pass width from your view and in the HTML, you need to access it.
<div class="star-ratings-css-top" style="width: {{ width }}%">. I tried these code snippet, working for me and should work for you as well :)
I'm really stuck in this subject and maybe someone can help me out. I can always generate a token with stripe successfully but somehow my charge function doesn't wan't to work. I'm using the stripe element from their official documentation.
How can I find out where I have to search for the mistake because I don't get any error from the code. In the stripe dashboard I can see the generated tokens, that's why I think until this point there is everything right but I guess my mistake is in the view function. More precise I think the view function doesn't get the generated token from the javascript. Many thanks for your help in advance!

I'm creating an MVC page that uses Kendo validation.
I have the following Model:
public class ForgotPasswordModel
{
[Required(ErrorMessage = " ")]
public string UserName { get; set; }
[Required(ErrorMessage = " ")]
[EmailAddress(ErrorMessage = " ")]
public string Email { get; set; }
public string PhoneNumber { get; set; }
[Required(ErrorMessage = " ")]
public string Code { get; set; }
}
I do not want my view to show Error Message for the Email field. I want it to show only exclamation sign when validation fails.
Currently I have the following code in my View:
#model Site.Models.ForgotPasswordModel
#{
ViewBag.Title = "Forgot Password";
Layout = null;
}

I do not want "Email is not valid" message to be displayed in case of regular expression validation fails.
I just need an exclamation sign.
How can I do that?
For your email field you can try adding data-email-msg attribute, which is way to customize the validation message for wrong email field value.
For ex: If you want to display a blank message for wrong value for email id you can do something like:
<input type="email" name="email" id="email" name="email" data-email-msg="">
And if you want to customize the required field validation message too, then you can add an another attribute data-required-msg as below:
<input type="email" name="email" id="email" name="email" data-email-msg="" data-required-msg="">
I have an input field. When the user clicks it some javascript converts the text to a Raphael JS library variable. I want to put each letter into a Raphael variable called string followed by a \n. When the user clicks on the button nothing is displayed. Can someone help me fix this?...

Instead of setting the variable string, you want add to it. Also, there were quite a few other updates I made to your excerpt...
Setting variables to reserved words can also cause a lot of problems.

Update:
To remove the previous text, it is just a matter of utilizing the Raphael remove function. Also we have to reset the variable something
if (alpha) alpha.remove();

You're not actually displaying anything. This line:
document.getElementById("letters").innerHTML + splittxt[i] + "<br>";
needs to be something like:
document.getElementById("letters").innerHTML += splittxt[i] + "<br>";
The value of the words input is blank => when you call the split method var splittxt = txt.split(""); the splittxt has a length == 0, and therefore the body of the for statement is never executed.
