[GUI Plugin] Reading Goal

[Feoras]

Hey there,

it's been awhile but thank you so much for all the improvements for this plugin and adding the bar/column daily chart!
Finally had some time to add all the books from previous years to the plugin too.

I just have one tiny issue ... that calibre closes without any error when I click on a month to open the daily chart.
I'm not quite sure why this happens. It happens with a dummy library with just one entry, column or line, no matter what calibre just closes.
To test if it is the daily html/code causing this, I replaced the starting monthly view with the daily view and this works - no crash.
Every other view works (genre, month, different year, all years).
So I am not sure what could cause this crash, especially since others do not seem to have this issue.
I am using calibre on Linux, so it might very well be an OS specific issue too ...

I'm sorry you having issues. I can't replicate the bug.If you have any more info, I would love to debug this

I figured out that the issue is somewhere/within the navigationRequest handling:

self.browser.page().navigationRequested.connect(self.daily_pages_columns)

I replaced the navigationRequested with buttons, and this works. E.g. this:

class ReadingGoalStatisticsDialog(Dialog):
    def setup_ui(self) -> None:
        # ...
        self.change_view_menu.addItem(get_icon('genre_view.png'), _('By genre'))
        self.daily_button_jan = QPushButton(_('Jan'))
        self.h_layout.addWidget(self.daily_button_jan, 0, Qt.AlignRight)
        self.daily_button_jan.clicked.connect(lambda: self.on_daily_button('jan'))
        self.h_layout.addWidget(self.change_view_menu, 0, Qt.AlignRight)
        # ...
    # ...
    def on_daily_button(self, month) -> None:
        # this is basically daily_pages_columns with only the part in len(url) == 3 and url replaced with month
        daily_page_count = self.daily_page_count()
        daily_data = [[_('Days'), _('Pages')]]
        temp_daily_data = []
        for day in daily_page_count[month]:
            temp_daily_data.append([str(day), daily_page_count[month][day]])
        for item in temp_daily_data:
            daily_data.append(item)
        h_axis_title = _('Days')
        v_axis_title = _('Pages')
        previous_button = _('Previous')
        next_button = _('Next')
        main_title = month.upper()
        background_color = '#121212' if is_dark_theme() else '#ffffff'
        text_color = '#ddd' if is_dark_theme() else '#000000'
        _daily_html_column = daily_html_column
        formated_daily_html_column = _daily_html_column.format(daily_data, background_color, text_color,
                                                         h_axis_title, v_axis_title, main_title,
                                                         previous_button, next_button)
        self.browser.page().setHtml(formated_daily_html_column)
        self.month_name = deepcopy(month).lower()
        self.months = [x.lower() for x in daily_page_count.keys()]
        self.year_menu.setFocus()

Though the question is why the navigationRequest connect function leads to this issue of calibre just closing.
Any idea?

Are you using a distro version of calibre or the oficial* version? It doesn't happen on windows. I don't have a linux machine at the moment to try this.

* sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

I am on arch, which seems to be quite behind on the calibre version in the official repository. It's currently on 8.7 while calibre github is already at 8.16. I have switched to the aur version (https://aur.archlinux.org/packages/calibre-bin) which uses the official build calibre which also bundles all libs (instead of the python system libs etc). With this version I have no crash.

Thank you again for all the work you have done. Loving the column daily view!
Have a lovely start into 2026

I'm glad it worked out. Distro versions of calibre are known to cause problems now and then. Happy new year.

You are doing it all wrong. You should go to the calibre site and get the official version from there. Don't use any repository as most don't have a clue what they are doing with calibre. And then you get an error, go and report it ony to find it's your version of calibre that's botched.

The latest version of calibre is 8.16.2.

The AUR automatically updates every 24h. So in worst case, the version from that AUR is one day out of date. I think Arch users will be fine, but with the benefit of proper autoupdates.

Boy are you confused.
You only get update notifications if the version.release is lower than installed. the .2 (hot fix) was 2 (emergency?) patches above the original 8.16.0. If that was installed... YOU DO NOT GET A NOTICE until 8.17

He is talking about the Arch Linux AUR repository update, not calibre itself.

That's not fully correct. You do get a notice for 8.16.2 when you are using 8,15 or earlier. I was using 8.15 and got notified of 8.16.2. But if you use 8.16 then you won't get notified of 8.16.2.

Hello, I am experiencing this error after installing the plugin: AttributeError: 'int' object has no attribute 'items'.

The error pops up when navigating the plugin menu, and many times while doing other things in Calibre unrelated to Reading Goal (eg, editing books).
I managed to add the custom columns in the plugin, but clicking all other areas in the menu results in the above error. I tried uninstalling and reinstalling the plugin but get the same error. Info is shown below. Thanks for the help.

Go to 'Config Dialog > Columns tab > Add to challenges' and delete the number there. If you want to use the auto add to challenges feature, you need to create a dictionary as explained in the tooltip. Anyway, I'll add a fix for this kind of mistake.

Thanks very much. This fix worked.
Thanks again for this feature. I was pleased to find a plugin that would give reading statistics like StoryGraph or Goodreads.

Hello everyone

For some time now, the plugin hasn't been working for me. I've included the error message at the end.

At first, I thought it was related to the new year, since I hadn't added any books for 2026 yet. But I can't add any more books or edit existing ones.

I've gone through my data to check for incorrect or missing values. I found one incorrect value (1000%) and corrected it, but that didn't work. Then I tried removing books with incomplete information, such as unfinished books or audiobooks, from the database. But none of the books were added.

I also tried the suggestion from "Yesterday 07:27 PM by thiago.eec:

Go to 'Config Dialog > Columns tab > Add to challenges' and delete the number there.

without success.

What am I doing wrong?

PS
My English isn't very good, and I also have no programming knowledge. So please excuse my clumsy description.
