join more than one table in spring jparepository -


i trying fetch record doing join. new spring jparepository. understand there separate repository each entity(table) when implement need define entity , datatype of primary key.

could please suggest how can fetch record joining 2 tables.

i have 2 repo below:

public interface aentityrepository extends jparepository<aentity, integer>  public interface bentityrepository extends jparepository<bentity, integer>

i want join above 2 entity(aentity, bentity). know can have custom query using below:

@query("select ****** aentity ae") aentity findcustomrrecords();

however can write same kind of query (join query) join. need have separate repository implementing other class.

can please help.

i using mysql.

i understand there separate repository each entity(table)

this common misunderstanding. not want have repository per entity, per aggregate root. see http://static.olivergierke.de/lectures/ddd-and-spring/

regarding specific problem @ hand: creating custom method in repository interface , annotating jpql should trick. like:

@query("select bentity b join b.a b.foo = :foo") aentity getallfooishas(string foo);

you can use join syntax jpql offers in query.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.
