Seasons have a color to show on the calendar. I need them in HTML format
(e.g., #123abc) in order to set as value to `<input type="color">`, but
i did not want to save them as text in the database, as integers are
better representations of colors—in fact, that’s what the HTML syntax
also is: an integer.
I think the best would be to create an extension that adds an HTML color
type, with functions to convert from many representations (e.g., CSS’
rgb or even color names) to integer and back. However, that’s a lot of
work and i can satisfy Camper’s needs with just a couple of functions
and a domain.
To show the color on the index, at first tried to use a read-only
`<input type="color">`, but seems that this type of input can not be
read-only and must be disabled instead. However, i do not know whether
it makes sense to have a disabled input outside a form “just” to show
a color; i suspect it does not. Thus, at the end i use SVG with a
single circle, which is better that a 50%-rounded div with a background
color, even if the result is the same—SVG **is** intended for showing
pictures, which is this case.
It is inside the “user menu” only because this is where Numerus has the
same option, although it makes less sense in this case, because Numerus
is geared toward individual freelancers while Camper is for companies.
But, since it is easy to change afterward, this will do for now.
However, it should be only shown to admin users, because regular
employees have no UPDATE privilege on the company relation. Thus, the
need for a new template function to check if the user is admin.
Part of #17.
I do not see the profile image as an “integral part” of the user (i.e.,
no need for constraints), hence i do not want to store it in the
database, as would do for the identification image during check-in.
By default, i store the avatars in /var/lib/camper/avatars, but it is a
variable to allow packagers change this value using the linker.
This is also served as a test bed for uploading files to the server,
that now has a better interface and uses less resources that what i did
to Numerus.
Now the profile handler needs to keep a variable to know the path to the
avatars’ directory, thus i had to change it to a struct nested in app,
much like the fileHandler does. It still has to return the HandlerFunc,
however, as this function needs to close over the user and connection
variables.
Part of #7.
This is the first form that uses HTMx, and can not return a 400 error
code because otherwise HTMx does not render the content.
Since now there are pages that do not render the whole html, with header
and body, i need a different layout for these, and moved the common code
to handle forms and such a new template file that both layouts can use.
I also need the request in template.MustRender to check which layout i
should use.
Closes#7.
It is a lot of code having to check the login variables inside the POST
handler, and i could not mark each input field individually as invalid
because the generic errors array i was using did no identify which field
had the error.
Thus, i use more or less the same technique as with Numerus: a struct
with the value and the error message. This time the input field does
not have the label and extra attributes because i believe this belongs
to the template: if i want do reuse the same form template, i should
create a common template rather than defining everything in Go.
The name is a bit different, however, because it has meaning both to the
front and back ends, as it needs to be exactly the same. Writing it
twice is error-prone, as with a rename i could easily forget to change
one or the other, and here i see value in having that in Go, because
it is also used in code.
