is not the same : cannot make storage with storage_t

[spiritEcosse]

good time of day, I would like to use this approach "Slow & size effective" to create a storage and I would like to take data exactly from the method (&GroupModules::getLanguageName, &GroupModules::setLanguageName)
i have this code

    inline auto userStorage(const std::string& name)
    {
        return make_storage(
                    name,
                    make_table(
                        "registries",
                        make_column("id", &Registry::m_id, primary_key()),
                        make_column("url", &Registry::m_url),
                        make_column("priority", &Registry::m_priority),
                        make_column("info_url", &Registry::m_infoUrl),
                        make_column("test", &Registry::m_test, default_value(false))
                        ),
                    make_table(
                        "group_modules",
                        make_column("id", &GroupModules::m_id, primary_key()),
                        make_column("language", &GroupModules::m_language),
                        make_column("name", &GroupModules::m_name),
                        make_column("region", &GroupModules::m_region),
                        make_column("language_name", &GroupModules::getLanguageName, &GroupModules::setLanguageName)
                        ),
                    make_table(
                        "modules",
                        make_column("id", &Module::m_id, primary_key()),
                        make_column("name", &Module::m_name),
                        make_column("description", &Module::m_description),
                        make_column("abbreviation", &Module::m_abbreviation),
                        make_column("update", &Module::m_update)
                        ));
    }

    template<class O, class T, class ...Op>
    using Column = internal::column_t<O, T, const T& (O::*)() const, void (O::*)(T), Op...>;

    using Storage = internal::storage_t<
    internal::table_t<Registry,
        Column<Registry, decltype(Registry::m_id), constraints::primary_key_t<>>,
        Column<Registry, decltype(Registry::m_url)>,
        Column<Registry, decltype(Registry::m_priority)>,
        Column<Registry, decltype(Registry::m_infoUrl)>,
        Column<Registry, decltype(Registry::m_test), constraints::default_t<bool>>
    >,
    internal::table_t<GroupModules,
        Column<GroupModules, decltype(GroupModules::m_id), constraints::primary_key_t<>>,
        Column<GroupModules, decltype(GroupModules::m_language)>,
        Column<GroupModules, decltype(GroupModules::m_name)>,
        Column<GroupModules, decltype(GroupModules::m_region)>,
        Column<GroupModules, decltype(&GroupModules::getLanguageName, &GroupModules::setLanguageName)>
    >,
    internal::table_t<Module,
        Column<Module, decltype(Module::m_id), constraints::primary_key_t<>>,
        Column<Module, decltype(Module::m_name)>,
        Column<Module, decltype(Module::m_description)>,
        Column<Module, decltype(Module::m_abbreviation)>,
        Column<Module, decltype(Module::m_update)>
    >>;

    static_assert(std::is_same<Storage, decltype(userStorage(""))>::value, "");

but I get an error on this line

static_assert(std::is_same<Storage, decltype(userStorage(""))>::value, "");

though I'm not sure if I was not mistaken

Column<GroupModules, decltype(&GroupModules::getLanguageName, &GroupModules::setLanguageName)>

help, please

column with setter and getter has a type like this:

internal::column_t<GroupModules, decltype(GroupModules::m_languageName), decltype(&GroupModules::m_languageName), decltype(&GroupModules::getLanguageName), decltype(&GroupModules::setLanguageName)>

try it. Also you can check equality line by line the same way you check storage equality.

i replaced this line

Column<GroupModules, decltype(&GroupModules::getLanguageName, &GroupModules::setLanguageName)>

on this

Column<GroupModules, decltype(GroupModules::m_languageName), decltype(&GroupModules::m_languageName), decltype(&GroupModules::getLanguageName), decltype(&GroupModules::setLanguageName)>

but i got the same error, at this place

static_assert(std::is_same<Storage, decltype(userStorage(""))>::value, "");

probably swears at this line, can i replace it

make_column("language_name", &GroupModules::getLanguageName, &GroupModules::setLanguageName)

with

make_column("language_name", &GroupModules::m_languageName, &GroupModules::m_languageName, &GroupModules::getLanguageName, &GroupModules::setLanguageName)

?

[fnc12]

can i replace it?

No.

Replace a column with setter and getter with this

internal::column_t<GroupModules, decltype(GroupModules::m_languageName), decltype(&GroupModules::m_languageName), decltype(&GroupModules::getLanguageName), decltype(&GroupModules::setLanguageName)>

thanks for the help, something does not work, I will return to "Quick & binary fat" - this work very well

[fnc12]

ok if you say so. Anyway there is another cute issue and I develop this feature but very slowly. Writing storage type explicitly is a very boring action and can be done automatically. So subscribe on this issue to received some news.

thanks a lot
