FIXME: docs and examples needed (dont' forget to tell about problems adding new fields on the fly) Implementation notes: ``_new`` field is used to indicate whether this is a new data table. `addField` could be used only for the new tables! If at least one record was appended to the table it's structure couldn't be changed. )namerstream_changed_new_ignore_errorsFct|trH||_|rt|d|_nFt|dt ||_nt |dd|_||_|r||_n$|j |j|_||_ t ||_ d|_ dS)afInitialize instance. Arguments: f: Filename or file-like object. new: True if new data table must be created. Assume data table exists if this argument is False. readOnly: if ``f`` argument is a string file will be opend in read-only mode; in other cases this argument is ignored. This argument is ignored even if ``new`` argument is True. headerObj: `header.DbfHeader` instance or None. If this argument is None, new empty header will be used with the all fields set by default. ignoreErrors: if set, failing field value conversion will return ``INVALID_VALUE`` instead of raising conversion error. zw+b)zr+brbr FN) isinstancestrr openr boolgetattr HeaderClassr fromStream ignoreErrorsrr )selffreadOnlynewrs O/var/www/histauto/venv/lib/python3.11/site-packages/tablib/_vendor/dbfpy/dbf.py__init__z Dbf.__init__]s. a   DI E#1enn #1mDNN&CDD  62..DIDK  C**,,DKK*55dkBBDK(II  c|jjSN)r closedrs rz Dbf.s 4;#5r!c|jjSr#)r recordCountr%s rr&z Dbf.s  (?r!c.d|jjDS)Ncg|] }|j Sr ).0_flds r z Dbf...s???Ddi???r!rfieldsr%s rr&z Dbf.s??DK,>???r!c|jjSr#r0r%s rr&z Dbf.s dk&8r!c(|jp |jjSr#)r rchangedr%s rr&z Dbf.sDM$HT[5Hr!cFt|x|j_|_dS)z8Update `ignoreErrors` flag on the header object and selfN)rrrr)rvalues rrzDbf.ignoreErrorss 9=eD  4#6#6#6r!c|jSr#)rr%s rr&z Dbf.s T(r!zError processing mode for DBF field value conversion if set, failing field value conversion will return ``INVALID_VALUE`` instead of raising conversion error. )docct|tstd|dkr|t|dzz }|t|krt d|S)aReturn fixed index.
